Dear all,
... Just another suggestion (from what I experienced in my environment):
Would it be possible to treat/convert
inetnum: 193.0.0.221
to
inetnum: 193.0.0.221 - 193.0.0.221
(the 'single host') ?
is there a possibilty for ambiguity?
I guess there is, especially if the last element is 0 (e.g. 194.152.133.0, which probably can be confused with 194.152.133.0/24). It cannot be ambiguous, however, if the last element of the dotted quad is an odd number.
Probably not if we have all 4 fields of the dotted quad included.
Maybe we c/should require 193.0.0.221/32 here to be on the safe side?
I would prefer this latter (i.e. requiring the /32). Janos

Me (because of beeing to young?) is very used to CIDR, so for me it would be rather clear that a dotted quad means a single IP, and not a network ;-)
I would prefer this latter (i.e. requiring the /32).
Would be ok as well (and coverd by the first proposal anyway) - but I think the latter might also be convenient - and, if documented as well, should not cause confusion. my 0.01$ lG uk -- ------------------------------------------------------------------------ Ulrich Kiermayr Zentraler Informatikdienst der Universitaet Wien Network Security Universitaetsstrasse 7, 1010 Wien, Austria ------------------------------------------------------------------------ eMail: ulrich.kiermayr@univie.ac.at Tel: (+43 1) 4277 / 14104 Hotline: security.zid@univie.ac.at Fax: (+43 1) 4277 / 9140 Web: http://www.univie.ac.at/zid/security.html ------------------------------------------------------------------------ GPG Key fingerprint = BF0D 5749 4DC1 ED74 AB67 7180 105F 491D A8D7 64D8
