The number of IPs we > have is less then /24 so... No, if you have less than /24 you can not set up authoritative reverse DNS. You need to contact your upstream provider and tell them what to set. You can set it up like you have it, but only your local subnet will get the correct information. The rest of the interenet will reverse resolve from your ISPs DNS servers. I recently did this with Verizon (we have a /25 and Verizon is our upstream) and they took care of it with little fuss. If your upstream provider gives you problems, just ask to speak to someone else in the support network. I'm sure they'll have _someone_ on hand that understands how to do this right. -Bill -- If a bird in the hand is worth two in the bush, then what can I get for two hands in the bush?
