Please note that these tests only test whether domains in the IS zone (i.e. domains with the ".is" ending) are set up according to ISNIC requirements on the given nameservers.

Check domain setup

Enter the canonical names of at least two name servers you would like tested. They must be registered with ISNIC, enabled and configured with the target domain. The server names should match the NS records of the domain.

Requirements for Domains

Domains in the ".is" zone must meet the following requirements:

  1. At least two active nameservers must be configured:
    1. All nameservers must meet the technical requirements
    2. All nameservers must serve consistent data for the domain (give the same responses to SOA and NS queries)
    3. All nameservers must be registered with ISNIC
  2. SOA records must be correctly configured:
    1. Primary nameserver correctly named in the MNAME field.
    2. Working mailbox of responsible party in RNAME field.
    3. Times (refresh, retry and expire) according to RFC1912 (section 2.2) .
  3. NS records must be correctly configured:
    1. NS records must match what is registered with ISNIC
    2. The TTL (time-to-live) for the NS records must not be shorter than 24 hours (86400 seconds).
