I want my domain name to point to my static IP address. Where should I start?
Create a host (A) record for your domain name set to your static IP.
This tells the world that both dns1.mydomain.com and dns2.mydomain.com host your domain and can provide authoritative answers to queries. Note that
There are some free DNS websites with severl useful resources. I used freedns.afraid.org for setting up mine to start with until I set up a server to host it myself.
Dyndns is good, but if your address is static you had to either pay for the service or continue to follow links in emails they sent to keep the dns active. I also found the free service rather limited.
