I hope you are not really using "domain.com" because that is a registered
domain that can confuse the issue. If you do not have your own registered
domain to use for private IP's, or it is just an example, you should use a
truly bogus domain.

If this is for local private IP, why not do your own DNS with local
forward/reverse zones added? But that is easiest if LAN IP's are static.

If it is a public IP, you could use a dynamic IP service (static name to
dynamic IP mapping). There are many, but I use no-ip.com, updated by
their client automatically from /etc/ppp/ip-up whenever pppoe connects.
I suppose you might be able to use dynamic DNS for private IP's from dhcp
related scripts. But better just to use static LAN IP's and your own DNS
for any local servers.
I use bind9 for local DNS and public caching. But the only remote syslog
I do is from my WAP to local Linux static IP.
