What is the difference between ccTLD suffixes like "co.in" & just ".in"?
A friend asked me this question & this is my attempt at answering it.
A country code top-level domain (ccTLD) is an Internet top-level domain (like .com, .net, .org) generally used or reserved for a country, a sovereign state, or a dependent territory.
Internet Assigned Numbers Authority (IANA) is responsible for determining an appropriate trustee for each ccTLD. Each country's trustee may assign registrars to sell domain names with suffixes pertaining to their country as per their policies.
A country code second-level domain (ccSLD) is a second-level domain to a country code top-level domain. Some domain name registries introduce a second-level hierarchy to a TLD that indicates the type of organization intended to register an SLD under it. For example, in the .uk namespace a college or other academic institution would register under the .ac.uk ccSLD, while companies would register under .co.uk. The complete list of suffixes including those for each country are available at PublicSuffix.org
The following are the domain name public suffixes for India, made available by INRegistry -

- .in
- co.in
- net.in
- org.in
- firm.in
- gen.in (general)
- ind.in (individuals)
- ac.in (Academic)
- res.in (Indian research institutes)
- edu.in (Indian colleges and universities)
- gov.in (Indian government)
- mil.in (Indian military)
The ".co.in" suffix was originally for banks, registered companies, and trademarks. Liberalization of registration rules in 2005 & promotion of the ".in" ccTLD has led to greater registrations. India has fewer registration restrictions, especially for foreigners, than other countries.
