How to know and verify the expiration date of a domain name
Domain Name System (DNS)
Thanks to the Domain Name System (DNS), we wouldn't have to log into a browser by typing in an IP address. For example, if we want to visit Google, we simply type http://google.com/ instead of typing http://126.96.36.199/.
DNS also helps to increase the number of domain names available; This happens because web hosting companies today use the same IP to share different names. The main entities that regulate domains globally are ICANN and NIC.
What are ICANN and NIC?
The Internet Corporation for Assigned Names and Numbers or Internet Assigned Numbers Authority (ICANN) is an entity founded on September 18, 1998, headquartered in Marina del Rey, State of California, USA; This organization is responsible for regulating domain names and IP protocol addresses globally.
The Network Information Center or Network Information Center (NIC) is the body in charge at national level to delegate and regulate the use of domain names belonging to its own territory, those of the Higher Geographic Level and those of the Third Level; for example, the NIC of Spain (ESNIC) is responsible for domains with the extension.es, .com.es, .org.es, .gob.es, among others.
What are the types of domain extensions on the Internet?
there three types of basis that ICANN assigns for domain name extensions on the Internet, which we will name below:
- Generic top-level domains (identified by the acronym gTLD, which stands for generic top-level domain).
- Geographic top-level domains (they are known by the acronym ccTLD, which is the country code of the top-level domain).
- Third level domains (TrLD).
Generic top-level domains
They are the ones we all know with com extensions, net, org, biz, info, among many others; they are not conceptually defined, within a specific territory; A page with the domain.com extension can belong to a European company or from anywhere in the world.
The geographic top-level domains
They are defined within a country or territory and, unlike the generic type, theirs extensions are two characters long ; as for example: ar for Argentina, co for Colombia, stands for Spain, fr for France; there are geographic domains for all the nations on the planet.
Third level domains
I'm there combination of generic and geographic, their scope is delimited by the country of origin. For example, a.com.es domain is classified as a commercial extension whose activities are subject to Spanish regulations.
How to check the expiration date of a domain name?
I domain names are unique in all over the world, they cannot be two equal directions; for example, there cannot be two pages on google.com, but there can be different extensions such as google.com and google.es. Therefore, we will show you several ways to check the expiration date of a domain.
