missing IPv4Address.is_reserved entry?

According to RFC5753 (http://www.rfc-editor.org/rfc/rfc5735.txt), the 
192.0.0.0/24
"[...] is reserved for IETF protocol assignments."

Hence:
$ svn diff ipaddr.py

hey, thanks for the patch. Before we accept it, our lawyers require that you 
sign a the 
CLA 
(linked from the main page). It should be fairly simple. Please let me know if 
this is 
something you can/can't do.

oh, and if you already have, please let me know under what address you signed 
it.

cheers,
/peter

ugh, can't i just transfer the copyright of those trivial(!) snippets to you 
(which i
hereby do for any past or future contribution of mine to ipaddr-py) ?

unfortunately it's the lawyers who insist on this, not me :-/

you're right though, this is super-trivial, and there really is not other way 
to implement 
it.

i'll get you that CLA signed. In the individual CLA, what do they mean by 
"Electronic
Signature:" my gpg fingerprint or something else?

you should just have to enter "I AGREE" in that box and then hit submit.

got the CLA, thanks. 

the ipv4 unspecified address looks to be 0.0.0.0/32, not /8, so I'm fixing that 
and 
adding a test case for it.

fixed in r137
