As .is domains can only be registered on a yearly basis, they cannot be renewed explicitly. To renew a .is domain you have to set the domain renewal mode or default renewal mode to AUTORENEW or RENEWONCE.
Following requirements for the name servers are obliged by the registry:
The nameservers must be registered with ISNIC.
Nameservers must allow connection to UDP port 53, and to TCP port 53 as well (see RFC5966)
SOA records must be correctly formatted:
Master nameserver correctly named in the MNAME field.
Working mailbox of responsible party in RNAME field.
Times (refresh, retry and expire) according to RFC1912
TTL for NS records not lower than 24 hours.
Correct NS records. Properly registered in the appropriate zones, both forward and reverse. I.e. the nameserver’s name must be included in the PTR record set for the nameserver’s IP address.
is registrants may use the RRPproxy nameservers in the future, if they cannot provide their own name servers that meet the requirements of the registry (special configuration, registration of the used name servers at the registry). If the name servers are not configured correctly during domain name registration, the domain will be parked and will remain inactive. An error will occur, if the registrant tries to update a domain with an incorrect name server configuration.
The usage of a role contact for owner and admin(e.g. Domain Administrator, Hostmaster etc.) is not allowed and will result in the suspension of the domain by ISNIC. in case of an organization, the company name can be splitted and used as first and last name.
