I'd say no, and your ISP may need to gain a working knowledge of bind views if they need to resolve 1812 addresses for their own needs without affecting customers who are using the ISP DNS servers as their resolver.
the way you could fix this without their involvement is to bring up your own DNS server which is master for the zone you are using internally. any queries it can't answer, will only then be forwarded off to your ISP. -g On Aug 9, 2010, at 8:09 PM, donovan jeffrey j wrote: > Greetings > > my isp has some private address space which has dns resolution and can be > queried from the outside world. > > I asked them about this because we use this private address space and it is > showing up in our DNS lookups. here was there response; > >> I've discussed this with our systems administrators and have been told >> that this is performing as expected.
