Måske du især skal overveje ispconfig, hvis du ikke er så rutineret:

hej jeg har nu fuldt din vejledning, men jeg for følgende fejl på alle mine nevneservere:

indeholder ikke NS record for domænet

NS-records identify the DNS servers responsible (authoritative) for a zone.

A zone should contain one NS-record for each of its own DNS servers (primary and secondaries).
This is mostly used for zone transfer purposes (notify messages).
These NS-records have the same name as the zone in which they are located.

But the more important function of the NS-record is delegation.
Delegation means that part of a domain is delegated to other DNS servers.
For example all ".com" sub-names (such as "simpledns.com") are delegated from the "com" zone (hosted by the "InterNIC").
The "com" zone contains NS-records for all ".com" sub-names (a lot!).

You can also delegate sub-names of your own domain name (such as "subname.yourname.com") to other DNS servers.
You are in effect the "InterNIC" for all sub-names of your own domain name (if you have a really cool domain name, you might even be able to sell sub-names for profit).

To delegate "subname.yourname.com", create NS-records for "subname.yourname.com" in the "yourname.com" zone.
These NS-records must point to the DNS server responsible for "subname.yourname.com" for example "ns1.subname.yourname.com" - or a DNS server somewhere else like "ns1.othername.net".

An NS-record identifies the name of a DNS server - not the IP-address.
Because of this, it is important that an A-record for the referenced DNS server exists (not necessarily on your DNS server, but wherever it belongs), otherwise there may not be any way to connect with that DNS server.

If an NS-record delegates a sub-name ("subname.yourname.com") to a DNS server with a name in that sub-name ("ns1.subname.yourname.com"), an A-record for that server (""ns1.subname.yourname.com") must exist in the parent zone ("yourname.com").
This A-record is called a "glue record", because it doesn't really belong in the parent zone, but is necessary to locate the DNS server for the delegated sub-name.
