Hi Daniel, re: > The question then is whether the current instantiation of > weather.southalabama.edu is covered under the blanket '.edu' exception. If reverse DNS exists for weather.southalabama.edu, then yes, it it is covered by the blanket ALLOW. A quick check using 'nslookup' shows that reverse DNS does, in fact, exist for this machine: % nslookup weather.southalabama.edu Server: 128.117.64.44 Address: 128.117.64.44#53 Non-authoritative answer: Name: weather.southalabama.edu Address: 199.33.132.237 % nslookup 199.33.132.237 Server: 128.117.64.44 Address: 128.117.64.44#53 Non-authoritative answer: 237.132.33.199.in-addr.arpa name = weather.southalabama.edu. Authoritative answers can be found from: 199.in-addr.arpa nameserver = z.arin.net. 199.in-addr.arpa nameserver = x.arin.net. 199.in-addr.arpa nameserver = r.arin.net. 199.in-addr.arpa nameserver = arin.authdns.ripe.net. 199.in-addr.arpa nameserver = y.arin.net. 199.in-addr.arpa nameserver = u.arin.net. r.arin.net has AAAA address 2001:500:f0::63 u.arin.net internet address = 204.61.216.50 u.arin.net has AAAA address 2001:500:14:6050:ad::1 x.arin.net has AAAA address 2001:500:31::63 y.arin.net internet address = 192.82.134.30 y.arin.net has AAAA address 2001:500:127::30 z.arin.net internet address = 199.212.0.63 arin.authdns.ripe.net internet address = 193.0.9.10 re: > If > this is the case, I don't foresee any issues with CSC setting up a DNS > entry for the new machine and either swapping around the cnames or moving > the current cname to an alias. Excellent! re: > If it isn't the case, then there is the > larger issue of finding out why rDNS isn't working in this context. It is the case that there is reverse DNS for weather.southalabama.edu, and because of the reverse DNS the machine will OK feed REQUEST(s) under the blanket '.edu' ALLOW.
