DNS AXFR of reservations?

[jg3]

Hi,

I have a bunch of DHCP resrvations with hostnames and they all resolve correctly.  Is there a way I can pull a list of all of them?  I mean, they're not really a zone (are they?) but I'm thinking along the lines of "dig -axfr localdomain @pfsense" … thoughts on how to do this?

This .. kinda works?

for a in {001..254}; do ans="`dig -x 10.1.1.$a @10.1.1.254 +short +norecurse`"; if [ $ans ]; then echo "10.1.1.$a    $ans"; unset ans; unset a; fi; done

(where 10.1.1.0/24 is my network and 10.1.1.1 is my pfsense)

… but man, that's just ugly.

You need BIND, PowerDNS, NSD or something equivalent that supports zone transfers, the dnsmasq and unbound forwarders/resolvers do not have that capability.
