Let me know if you have further questions.
Sure, but this adds undue load on my nameserver, and those of my customers for zones which I know will *never* change.
A DNS lookup may only take you a few milliseconds, but when you're running on a CDPD modem, 19.2K/s with 2-4 SECOND latency (typical while roaming off-network), having to wait an extra 15 seconds for a DNS lookup every 5 minutes is a pain.
On the other hand, when I'm planning an IP change of some sort which cannot
have redundancy on two IPs, I usually set my TTL to 60 seconds, that way
users experience almost no downtime (a maximum of 60 seconds, so in reality,
an average of 30 seconds or less)
Dave, I believe what you are looking for is called (or at least could be a part of) Dynamic DNS.
But we do not offer this service yet.
