Which RFC?

Anyone remember the RFC# that details the suggested email user names for
specific operations? i.e. dns-admin for DNS, abuse for Abuse, postmaster
for mail problems, noc for technical problems and requests, and peering
for peering request/problems etc. If anyone remembers what is is,
could you please email it to me? (I do not wish to furthur muddle up the
list.)

It was published last month as RFC 2142.
