Thread Index [isp-dns] Re: script to list nameservers
If your resolver is not the authoritative server for these domain names, you can do this: make a file called 'foo' with the domain names in it, and run: $ for zone in `cat foo`; do echo "**$zone" >> output; dig $zone NS | grep "IN NS" >> output; done If you are using a more recent version of dig, this won't work (the grep "IN NS" won't get any hits). If your resolver *is* authoritative for the domain names, you'll have to use a different resolver (because your auth server will just return that all domain names are delegated to itself): $ for zone in `cat foo`; do echo "**$zone" >> output; dig @other.name.server $zone NS | grep "IN NS" >> output; done This will give you a file called output that should look like: **foo.com foo.com 1D IN NS ns1.customer.com foo.com 1D IN NS ns1.customer.com **bar.com bar.com 1D IN NS ns1.customer.com bar.com 1D IN NS ns1.customer.com **baz.com baz.com 1D IN NS ns1.otherisp.com baz.com 1D IN NS ns1.otherisp.com On Tue, 1 Jun 2004, Andrew P.
