Any chance of making this:
result="$(gethostbyname "$1" "ns.dyndns.org")"
if [ -z "$result" ]; then
be conditional? If you're not using dyndns, then that's a lot of useless
lookups for nothing.
It's also a potential security hole, since you're revealing who you look
up to a 3rd party which you might not have any relationship with.
