Summary: nathelper does not detect RFC 3330 ranges

Initial Comment:
http://www.rfc-editor.org/rfc/rfc3330.txt

RFC 3330 defines a number of range which can not be found on the internet and if used are being nated.

nathelper does not detect those range like it does for RFC1918 ones.

Some of the ranges defined are marked as possible for allocation so I performed the whois request to check which one had been (and only one was found).

$ whois -h whois.radb.net 39.0.0.0
route:         39.0.0.0/8
descr:         Exchange Point Networks
               PO 12317
               Marina del Rey, CA. 90295
               US

$ whois -h whois.radb.net 128.0.0.0
%  No entries found for the selected source(s).

$ whois -h whois.radb.net 191.255.0.0
%  No entries found for the selected source(s).

$ whois -h whois.radb.net 192.0.0.0   
%  No entries found for the selected source(s).

$ whois -h whois.radb.net 223.255.255.0
%  No entries found for the selected source(s).

Those are not relevant :)

   224.0.0.0/4          Multicast                              [RFC3171]
   240.0.0.0/4          Reserved for Future Use        [RFC1700, page 4]

I've looked up the ranges the original poster specified in the RFC.
128.0.0.0, 191.255.0.0, 192.0.0.0 and 223.255.255.0 will be probably
allocated sometimes. There a some special cases (like performance tests,
example code) in this RFC that make no sense at all. So i don't think this
is a real issue.

Please reopen if you have another range(s) in mind.

Henning

Hi,

the RFC3330 defines groups of IP for special purposes, but not necessary
for private networks. What are the ranges you think that can be used only
in private nets?

Regards,
Bogdan
