With traditional DNS software, you'd need there to be a SOA record
at 55.3.10.in-addr.arpa for you to be able to AXFR just that set of
records.  If the only SOA is at 10.in-addr.arpa then it'll barf
trying to grab just a subset of that.

With a SOA, you also need NS records, and if there are any other slaves
they'd need to be configured to secondary the new subdomain in addition
to the existing parent.

Odds are that unless you're on dialup, or there are records the master
doesn't want you to see, just copying the whole zone may be less
trouble than trying to divvy it up.
