Does something like this exist? - replacing IPs in A records

This is probably not possible (?), anyway. I am moving 1200 web sites to other servers and has to manually change the IPs of two A records (ns1) in the ´DNS zone files. The majority uses the same nameservers/IPs but some uses their own private nameservers so the IPs of these A records are different. - Did any clever person out there write a script that browses through the zone files and changes them all in one hit?. I'm an optimist Does something like this exist? - replacing IPs in A records

Thanks
John
