I insert foot in mouth in article <6184@uwmcsd1.UUCP>, where I say:

Jon Postel in article <8807090341.AA04490@bel.isi.edu> replies:

> ... please read RFC-1009 pages 14, 15, 35, 36, 44, 45.

Indeed, RFC 1009 states in the text that "-1" is "all one bits".  I stand
corrected on this matter.

Assuming "-1" is "all ones" is, to me, a 2's complement bias.  Coming from a
1's complement environment, I misinterpreted this and shot my mouth off.
Sorry, folks.  I'm just learning about all this network stuff.

[I still have a problem with some wording in RFC1009, but am not sure this
is the proper place to raise it.  Can someone advise me on this?]
