Also, with a short DNS, I think the lowest you can go is 1 minute. So<br>
even with we had a firewall that could dynamically update, there will<br>
still be a 1 minute outage every time the IP flips.<br>

DNS administrators will hate you for life, make fun of you in public, and perhaps vandalize your cube if you do this though because their infrastructure is getting hit for EVERY request, rather than once for each client every so often.<br>
