Eric, Odd. Every time I renumbered some site (hq.af.mil and sundry other sites sharing similar characteristics), there was neither a NAT prior to, nor subsequent to, the renumbering. If they are already using NAT, it is most likely they wouldn't need your services to renumber, no? Rgds, -drc

Keith, a 92.55% reliability rate is not exactly impressive, at least not in a favorable sense. it might be tolerable if a failure of the PTR lookup doesn't cause the application to fail. If people's livelihood depends on something, they're more likely to insure it actually works. Very

Charlie, DNS is supposed to be a way to resolve domain names into IP addresses. As a hammer is supposed to be a way to pound nails. However, when it is perceived that all you have is a hammer, it is amazing what begins to look like nails. How else would one get an IP(v6) address from a
