Doesn't RFC 4193 already define "site" in a way that is clear for ULAs:
3.3. Scope Definition By default, the scope of these addresses is global. That is, they are not limited by ambiguity like the site-local addresses defined in [ADDARCH]. Rather, these prefixes are globally unique, and as such, their applicability is greater than site-local addresses. Their limitation is in the routability of the prefixes, which is limited to a site and any explicit routing agreements with other sites to propagate them (also see Section 4.1). Also, unlike site-locals, a site may have more than one of these prefixes and use them at the same time. A site (or site-of-sites to use the MANET terminology) is defined by the routability of a particular ULA prefix. - Bernie -----Original Message----- From: Templin, Fred L [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 12, 2007 5:49 PM To: Paul Vixie; IETF IPv6 Mailing List Subject: RE: Revising Centrally Assigned ULA draft > so my previous question stands. what's a "site"? Paraphrasing from the 'draft-templin-autoconf-dhcp' definition for "Mobile Ad-hoc Network (MANET)": site a connected network region that comprises routers that maintain a routing structure among themselves. A site may be as large as an Autonomous System (AS) or as small as an individual router, and may also be a subnetwork of a larger site. A router (and its downstream-attached links) is a "site" unto itself, and a site can therefore also be considered a "site-of-sites". (Note that the only distinction drawn between "site" and "MANET" is that some MANETs are less mobile and ad-hoc than others - and, we would simply call those: "sites".)
