problem setting nameservers for a .de domain

[keithjenkins]

Has anyone successfully set the voda27 nameservers to a .de domain? I tried but after several attempts emailed their support team. The below criteria was what I received. Can anyone explain the relevant parts as I'm sure vodahost meets most of them

When modified for a .DE domain name, the new nameservers must meet the following criteria:

Refresh rate between 10000 and 86400 seconds

Retry rate between 1800 and 28800 seconds

Expiration rate between 604800 and 3600000 seconds

Resource record TTL (Time To Live) between 180 and 345600 seconds

The following criteria must also be met:

The domain MX record must resolve to a mail server that is valid for the life of the domain registration.

The DNS servers must be located on two distinct class C networks.

The zone files for both nameservers must have matching serial numbers.

The primary and secondary hosts specified in both zone files must match the first and second nameservers entered.

Thanks in advance for any help anyone can give. I don't understand any of it.

Re: problem setting nameservers for a .de domain

On further investigation, my IP address that starts with 67. could possibly be a class A network and not meet their class C requirement. Does this sound likely and how would I get a class C IP address if it IS the case?

thanks
