NIC handle


A NIC handle is a unique alphanumeric character sequence that represents an entry in the databases maintained by Network Information Centres. When a new domain name is registered with a domain name registrar, a NIC handle is assigned by the registrar to the particular set of information associated with that domain name. Once a domain name has been registered, its NIC handle can be used to search for that record in the database.
The NIC handle was developed in 1982 by Ken Harrenstien and Vic White working at the early Network Information Center at SRI International.

NIC handle system in limited modern use

The NIC Handle system is no longer commonly used by domain name registries.
It was previously possible to query WHOIS by NIC handle, and see all the domains registered by that NIC handle, but this service was discontinued.
NIC Handles are still used extensively in the to identify people and business roles.
