2) What about /32 subnets? Is anyone using them? (see the links below that discuss how they're used...)
Yes these are use in many Cisco shops ..I use these all router for loopbacks. I like to see them on my maps -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Richard E. Brown Sent: Friday, March 02, 2007 1:14 PM To: [email protected] Subject: RE: [IM-Talk] /31 network masks Folks: Thanks for the spirited discussion of how you use various kinds of subnets. It's helpful to hear all this so that InterMapper can "do the right thing" for our customers. In pursuit of this goal, I'd like to expand the discussion so that we can understand all the possibilities. 1) /31 subnets. It seems as if there are proponents of both sides: people who never intend to deploy a /31 subnet, (and want a facility to warn them if they've done so); and people who regularly use them on point-to-point links as described in RFC 3021. 2) What about /32 subnets? Is anyone using them? (see the links below that discuss how they're used...) 3) Are there other unusual subnets/related network configurations that we should take into account? My question to the group: What should/could *InterMapper* do when presented with equipment that uses any of these configurations? I've googled around and come up with a few citations on the subject. See the links at the bottom of this message. Many thanks!
