Export list of name servers

We have 14 DNS zones, each with a list of 20 - 30 name servers in the zone properties. I need to list all of the name servers for each DNS zone, so we can try to clear out some of the legacy servers.

Is there a quick way to export the name servers list, without having to go through each one on the list, and copy & paste it individually into a text file?

Create a text file with the following contents:
set type=NS
<zone1>
<zone2>
.
.
.
<zone14>
exit

from the CMD prompt, "nslookup <filename >outputtxtfile.txt"

Does that give you what you were looking for?

And just to make certain the command line syntax is clear...  you are redirecting in with '<' the commands to nslookup, and you are getting the output to a text file via the redirector '>'.
For my test here, I created a file called temp.txt and put the set type command and zone list in... so when I ran the command, it looked like this:
nslookup <temp.txt >output.txt

Hi,

Yes just ran it, and it worked perfectly! One thing I did notice was the number, and order of the nameserver list, and internet address don't always match. i.e.

uk.domain.com nameserver = ns01.uk.net
ns01.uk.net      internet address = 10.0.0.20

My first zone had 54 name server records, but only 50 IP addresses, and the order didn't match. owever this isn't important, as I'm only interested in the name server names, not IP addresses, but it's worth noting!

Many thanks, you have saved me many laborious hours of copy & pasting!
