Though why one would want to do this rather than just updating the
zone using DDNS is beyond me. It's not like DDNS can't be made
secure by using TSIG.
Normalize the zone file using named-checkzone.
Use awk or similar to change the relevent entries and update the SOA serial.
Use named-checkzone to confirm that the resulting file is still valid then
if it is rename it and reload the zone.
named-checkzone -D -q zone file |
awk '$1 == "server" && $4 == "A" { print $1, $2, $3, $4, NEWIP}
$4 == "SOA" { $7 = $7 + 1; print }' > temp
named-checkzone -q zone temp && mv temp file && rndc reload zone
