Still learning here, so please go easy... I read the above, and I see section 4 item 3 says: The author feels that if /64 cannot be used, /112, reserving the last 16 bits for node identifiers, has probably the least amount of drawbacks (also see section 3). I guess I'm missing something; what in section 3 is this referring to? I can understand /64 or /126 (or maybe /124 if you were going to delegate reverse DNS?), but why /112 and "16 bits for node identifiers" on a point-to-point link? -- Chris Adams <cmad...@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
