Important site-specific Notes

Hosts

Adding hosts should work normally.

When you choose the domain for your host, be careful:

• The nsupdate.info domain is offered and controlled by us.
• Other public domains are offered and controlled by other users of this service. Availability of these is up to them.
• Please have a look at the owners and their comments about the available domains in the domain overview.

Domains

If you add an own domain (not just a host), your nameserver address must be IP v6, which can be achieved in 2 ways:

• your nameserver has a native IPv6 address - just use it!
• your nameserver only has IPv4 (e.g. 192.0.2.33), then create a IPv6 address like shown below and enter it into the nsupdate.info form field:

       +-------------------+--------------+----------------------------+
       | Well-Known Prefix | IPv4 address | IPv4-Embedded IPv6 address |
       +-------------------+--------------+----------------------------+
       | 64:ff9b::/96      |  192.0.2.33  | 64:ff9b::192.0.2.33        |
       +-------------------+--------------+----------------------------+
       (taken from RFC 6052, section 2.4)
  
       NOTE: due to changes in tayga, this does not work any more since we
       moved to a new VM host at 2021-11-06.
  
       An immediate fix is possible if you can enter a valid public IP v6
       of your DNS server.
  
       If that is not possible, make sure your DNS server has a valid A
       record at least, so it can be referred to by FQDN.
       With that and a fix to the nsupdate.info code, we can make
       it working later again based on the FQDN of your nameserver.
      

We require IPv6 because the machine that runs this service only has v6 connectivity.

Updates to external IPv6 DNS servers should work now, see: issue #140
