Thanks. I thought of that, but I'm going to need more explanation and
help. I understand that I can use something like nsupdate to update DNS
records, but then I'd need to install and configure a compatible DNS
server - the one I currently use, dnsmasq, apparently doesn't support
RFC 2136 updates. Is there something I'm missing?

Additionally, I'm using simple hostnames, not FQDN names. Will that
still work with dynamic DNS?
