The *.undernet.org are a special thing. The non-existing forwards are on purpose.

---------------------------------------------------------------------- o Server name in the SOA record differs from server name in an NS record The name server with the IP address 213.136.0.66 is identified by the name "ns.bit.nl." in the SOA record but the NS record uses the name "ns1.bit.nl." for the host.
Same box. Non-issue but fixt anyway.
o All name servers for the zone are on the same subnet. All name servers for the zone are on the same subnet (213.136.0.*). If the connection to the network breaks, your domain will become inaccessible.
Which brings us partly back to the originating discussion. 213.136.0.66 and 213.136.0.77 do not necesarily have to be on the same subnet. -- Sabri Berisha - www.cluecentral.net - "I route, therefore you are" - nooit meer naar Bonaire: http://nu.nl/document?n=59946 - "Waarom draait er een mailserver op die $mailserver?" - Pim van Pelt
