What is a domain name?
Domain names are the equivalent of street addresses, but for websites. To get to any web site, directly, in a web browser (i.e. without using a search engine), we will need to know its domain name.
A domain name is a set of letters, words, numbers, and the occassional hyphen. (Example: Google.com, Reddit.com, etc) When you type domain name into a web browser, the website will appear if the domain is in use.
A domain comes in 3 parts:
- The top-level domain – (AKA the TLD”) This is the .com part of the domain. (Or .net, .org, .info, etc)
- The root domain – Is the main part of the domain or what comes before the TLD
- The subdomain – Is what comes before the root domain. Often by default, this is “www” which is a defauly sub-domain that is used less and less these days and almost never required anymore.
Common Mistakes with Domain Names
- Not ebabling privacy protection
When you buy a domain, you are required to list contact info for the “Registrant” of the domain which is the person or entity that owns it.
The contact info for that Registrant then becomes part of publicly available records in the big master database of all domains, which is called the “WHOIS” database. This means that spammers, hackers, etc can easily find out who owns any given domain and potentially target them.
- Not keeping contact info up to date
This is very common and leads to problems later.
- Not having a payment method setup for renewals
- Changing web vendors who host your DNS for you
What Does DNS Stand For?
The acronym itself stands for Domain Name Service but you also see it used for Domain Name Servers or Domain Name Scalpers in the domain aftermarket. (I just made that last part up)
