Hey Lamar, long time no talk.

Standards are written by people, of course, and most paragraphs have reasons to

filling a slot in its neighbor table for a host that doesn't exist. For that
matter, I'd like to see a pointer to which standard that says this so I can
read the verbiage myself, as that may have enough explanation to satisfy my
curiosity.
This actually came up last week in freenode/#ipv6; someone was puzzled
why there were FAIL entries showing up in their neighbor table, so I dug
into the RFC I found for ND (2461). Turns out, it specifically says
entries for failed solicitations SHOULD be deleted.
http://tools.ietf.org/html/rfc2461#section-7.3.3
It's the seventh paragraph into that section, including the indented
Note. ("Upon entering the PROBE state...")
Pardon me if that's the wrong RFC.
