Every entity registered with InterNIC has a NIC handle. For example, Onlinecorp.com has a NIC handle of ek6-br that contains our address and contact information, so that we need not enter this information each time a new domain name is registered. You can use the same NIC handle as contacts for several domains. This way, if you make a change to the NIC handle (i.e., the email address), all domains using that NIC handle will be updated as well.
