How Does This Effect Case Sensitivity
Servers using Windows operating systems ignore case sensitivity when it comes to URLs.
Meanwhile, servers that run Linux or UNIX systems will identify capitalization on different websites.
If the server of your website migrates to newer machines, this would mean preparing to redirect your existing pages.
If the new server runs Linux, your once non-case sensitive URLs become case sensitive now.
Can You Make A Url Case Sensitive
As mentioned earlier, URL case-sensitivity depends on the operating system of your websites server. If you want to make your URLs case sensitive for the different pages of your site, use a Linux or Unix-based server.
But as mentioned earlier, having case sensitive URLs may cause problems later on the maintenance side.
This is why it is still best to have your pages in the lower case to reduce linking or redirection problems in the future.
How Do You Look Up A Fully Qualified Domain Name
Looking up the FQDN of your computer or server is simple. Just follow the instructions for your operating system below. If your machine does not provide the FQDN, it is not connected to a domain.
Windows 10. Within the taskbars Search Windows box, type control panel and select system and security. Next, select system and the FQDN is listed next to the Full Computer Name label.
Mac OS. Open terminal, and enter hostname -f into the prompt. Terminal will return the FQDN.
Linux. Open terminal and enter hostname -A into the prompt. The A is case sensitive. Terminal will return the FQDN.
Once you know your Fully Qualified Domain Name, you can make your device available online through the DNS.

Does Case Matter In Domain Names
Domain names are not case sensitive and whether you type in a domain in capital or lower case, you will end up on the same website.
For example, if you searchjoshuageorge.co.uk andJOSHUAGEORGE.CO.UK, you will end up on my home page no matter what.
Whether you search for the upper case or lowercase version, you will end up at the root domain of a page. Search engines deal with domains in lowercase letters and this is the same for every website.
What Is Case Sensitivity
Case sensitivity differentiates between uppercase/capital letters and lowercase/small letters. EXAMPLE and example are two words, but the first has uppercase letters that the second doesnt. These two words are the same in the context of meaning, but the uppercase letters make the difference.
The input field that differentiates the upper & lowercase letters in their action is a case-sensitive input. Here, the password field is case-sensitive, whereas the username field isnt. Most of the time, accidental use of the caps lock button will not affect the email address to be recognized by most of the servers.

Should Urls Be Capitalised
Generally, you should avoid using capitalised characters for your URL names. Using upper case letters for URLs makes them slightly harder to read as a pose to lower case and doesnt look too natural when a user lands on your website.
Whilst capitalised URLs will not make a difference in terms of the page location, you should generally avoid this. If your URLs also depends on the structure of your subcategories, some of your folders may pull in lower case with the URL of your page pulling in upper case.
Are Email Addresses Case Sensitive
I’ve read that by standard first part of e-mail is case sensitive, however I’ve tried to send e-mail to name@example.com, Name@example.com and NAME@example.com – it has arrived in each case.
How do mail servers handles usernames? Is it possible to miss with case and that message wouldn’t be delivered? Is it really very important to use exactly same letter case, as was written while registering when giving your e-mail address?
From RFC 5321, section 2.3.11:
The standard mailbox naming convention is defined to be”local-part@domain” contemporary usage permits a much broader set ofapplications than simple “user names”. Consequently, and due to along history of problems when intermediate hosts have attempted tooptimize transport by modifying them, the local-part MUST beinterpreted and assigned semantics only by the host specified in thedomain part of the address.
So yes, the part before the “@” could be case-sensitive, since it is entirely under the control of the host system. In practice though, no widely used mail systems distinguish different addresses based on case.
The part after the @ sign however is the domain and according to RFC 1035, section 3.1,
“Name servers and resolvers must compare in a case-insensitive manner”
In short, you are safe to treat email addresses as case-insensitive.
Way late to this post, but I’ve got something slightly different to say…

Why Is A Url After The Domain Name Case
While the actual domain name is not case sensitive, the full URL to a specific webpage on the domain may be case sensitive. Lets say, for example, you have a page called product.htm on your website. So the URL to this page will be https://yourdomain.com/product.htm. This URL is not the same as https://yourdomain.com/PRODUCT.HTM.
For the same reason that links within a website should match the letter case of the name of the file they actually link to, the address after the .com needs to match the letter case of the specific file or folders name. In our earlier example, although the domain is valid, the product.htm file name is in upper-case in the second example, and that file may not actually exist on the server.
In other words, yourdomain.com/product will go directly to a page on the webserver that is in a folder named product. This wont work with PRODUCT because there is no folder on the server with that name.
Operating systems treats a file with different letter-casing as a different file. In our example, because the PRODUCT.HTM file does not exist on the server, your browser will generate a 404 error message.
Is Domain Name Case Sensitive
In this post you will get a simple answer to your Is Domain Name Case Sensitive? question, and useful information about case sensitiveness in URL parts.
Answer:
Domain names are case insensitive. It means, if you write domain name in uppercase, lowercase or mix, then in all cases you will land on the same page.
For example,
If you type in the browser https://techpostplus.com, https://TECHPOSTPLUS.COM or https://TechPostPlus.com, then in the result your browser will open the same page for all cases.
Domain name case insensitivity helps to create uniqueness between domain names.
Note:
In URL, string after the domain name is case sensitive.
e.g., https://example.com/page-name.html URL is different from https://example.com/PAGE-NAME.HTML.

Your domain name is significant to your branding.
Registering a domain name does not automatically get you all possible variations of your website URL.
This is why it is recommended that you get all possible permutations of your domain name, including .com, .net, .org, among others.
While it may come out as expensive, this brings peace of mind for big brands and businesses who want to protect their brand from misuse by competitors.
Case Sensitivity Of Domain Names
Normally the DNS uses an ASCII based encoding system which results in case-insensitivity to domain names this encoding system only uses ASCII-based and Latin-based characters to form domain names.
Most of the domains you see around you use this system. Thats why we said earlier that writing facebook.com like FACEBOOK.COM wont make any difference.
Not only this, but you can also write Facebook.com as
FaCEbOOK.COM
Facebook.COM
It makes no difference.
Rather, when you buy the domain, only at that time do you get that domain in lowercase characters. You would never see your search bar showing domain/internet name in uppercase letters, Thats because your browsers automatically convert uppercase names to lowercase names.
If you are new to blogging then you do not need to think about these case sensitivity and insensitivity.

You Cannot Change A Domain Name
The only way you can change a domain name is to buy another one and transfer your current website to it. Domain names don’t have a EDIT button somewhere. Once it is registered it is done.
TIP: When choosing a domain name keep it as short as possible. Keep your keywords and leave out any extras. I recommend not using more than 2 words in a domain name. The longer your domain name the more difficult for your website visitors and clients to remember it.
A catchy and easy to say and remember domain name is ideal. I know this is not always possible but keep it in mind.
In the image above my domain have 2 words. Insensitive domains. I did not include “for everyone”.
Elements Of An Email Account
You dont need to be a technology expert to understand how the email address works. An email address has three different parts
- Top-level Domain
User Name
The text you type before the @ sign is your Unique Name or User Name. This section represents the local section of your email address. This section will allow the web to locate you precisely.
The User Name or Unique Name can contain digits and 64 Latin characters. You can use periods in this address section, but not as the first or last character.
Domain Name
Take a glance at the given picture above. The provided information after the @ symbol is called Domain. It indicates the email server and the web address by which you send an email. A random domain doesnt have its server, so you cant use an arbitrary one. You have to make sure that this part refers to your email and that its server truly exists in the first place.
The domain name must not surpass 63 characters. This part of the email address contains numbers 0-9 and 255 Latin characters.
Some common domains are Gmail, Yahoo Mail, Outlook, etc.
Top-Level Domain
The final part of your email address is the Top Level Domain, and it takes place after the dot . symbol. There are two types of TLD.
- Country-specific
Other Parts of an Email Address
Besides these three major parts, there are some other parts of the email address that you should know.
@ symbol

Is There An Option Available For Importing Matching Sets Of A And Ptr Records
Yes. There’s a shorthand available for this when using the zone file importer. To use the zone file importer, select Import zone file from the DNS record group page. Once there, enter the matching A and PTR records using the following format:
ip-address < => domain
For example, to import a reverse DNS record for “1.2.3.4” that maps to example.com., and an A record for example.com. that maps to “1.2.3.4”, enter:
1.2.3.4 < => example.com.
To import a reverse DNS record for example.com that maps to “2604:a880:800:10::7a1:b001”, and a corresponding AAAA record, enter:
2604:a880:800:10::7a1:b001 < => example.com.
See the “Reverse DNS Shorthand” section of our Reverse DNS Records documentation for more information.

I never thought that someone would have this question. But I was completely wrong! There are tons of people who dont know if domain names are case sensitive or not.
So are domain names case sensitive? The ASCII-based domain names are not case sensitive. However, we now have Internationalized Domain Names , which may seem like they are case sensitive. But in general, the intent of domain names is to be case insensitive.
I know you are scratching your head, so let me explain in plain simple English.
Are Domains And Urls Case Sensitive
Domain names are not case sensitive, but there are times when URLs are. This means you can enter a websites URL in all capital letters, and it will still bring you the designated homepage, but a URL depends on the server that hosts the site and whether or not it supports different cases.

Domain names are not only used in internet browsers, but they also abound offline, as well. Your domain name likely appears on your stationery, your business card, brochures, and other marketing content media.
In any URL, upper-casing is optional but only up to the .com part. Internet addresses become case-sensitive after the .com . When advertising your URL , it is okay to use upper-case letters in the domain name part of your websites URL for emphasis, distinction, or easy reading.
yourdomainname.com could be printed on your letterhead as YourDomainName.com and you can still be confident that your potential customer will find your website.
Furthermore, it pays to consider the aesthetics of your domain name on print media. The first consideration in this aspect is the use of upper and lower case to enable identification of separate words within that name and help clarify its meaning.
It is not only rude or questionable misinterpretation or association that can cause problems when multi-worded domain names are presented offline. Confusion or misreading may happen when consecutive words in a domain name end and start with the same letter. Some might even construe it as a misprint. Upper-casing, where such words join, will help distinguish the words.
Do Capitals Matter In Urls
Its just convention. Capital letters are commonly used in Wikipedia, YouTube and Twitter URLs if the article/channel/username has capital letters. All caps are rarely used because its considered loud and harsh, but there is nothing technical preventing it. URLs are not case sensitive up to a point.

Domain Names That Are Not Case Sensitive
Traditionally, the Domain Name System has had ASCII-based domain names. ASCII is nothing but a character encoding standard for electronic communication.
All such domain names that are based on ASCII are not case sensitive and will continue to be so.
The domain names that you see in daily life like , CNN.com, etc. are not case sensitive at all.
So it does not matter whether you type amazon.com, Amazon.com, AmaZon.com, or something else in your browser, you will be taken to Amazons website.
This is true for a majority of the domains in the world, even for domains that end with .gov, .edu, .net, .org, etc.
And it makes perfect sense to do so because you dont want your customers or website visitors to get confused and land on some other website.
If you were to register a domain name for your business, I think you will want your domain name to be case insensitive as well.
Alright, with that out of the way, let me explain a catch in all this.
While the actual domain name is not case sensitive, the complete URL to a specific page on the domain can be case sensitive.
Confused? I know. Let me explain
Lets say you have a page called product.htm on your website. So the URL to this page will be https://yourdomain.com/product.htm
This URL is not the same as https://yourdomain.com/PRODUCT.HTM
So if you try to go to the second URL with all capitalized letters, you will get a 404 error . This is because there is no page called PRODUCT.HTM on your website.
