No, waste is not an argument. The main argument for both /127 and /126 is to avoid having unused addresses on a link. But /126 will still leave one adress, which is why some prefers /127 instead. Although this does mean that you have to ignore the router anycast address. > http://tools.ietf.org/html/rfc3627 Well, that's one informational opinion. There's also the recent standards track opinion: http://tools.ietf.org/html/rfc6164 The nice thing about standards is that there's so many of them :-) Bjørn -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
