[IDD #GJH-813065]: Request for another server for UNIDATA LDM access

Hi Daniel,

re:

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

Excellent!

re:

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.

Cheers,

Tom
