It's either the magellan or 18.104.22.168.in-addr.arpa
query, I'd say. You can reproduce these manually with
dig magellan @127.0.0.1 (or actually dig magellan aaaa @127.0.0.1)
dig -x 22.214.171.124.in-addr.arpa @127.0.0.1
If you configure your BIND/diald/ISDN/whatever such that
your internet connection is not started by these two
digs, then it shouldn't get started on that ssh either.
Also, if you are not using IPv6, try ssh -4 magellan.
If you are using 2.3 kernels, try with 2.2.
