[mod.map] domains to become dotted with June posting

mark@cbosgd.UUCP (Mark Horton) (05/16/86)

Effective with next month's posting, we're going to adopt the
dotted domain convention that the most recent (Jan 86) pathalias
uses for the UUCP maps.  This means that all domains will begin
with a dot.  For example, the old
	ucbvax = "Berkeley.EDU"
becomes
	ucbvax = ".Berkeley.EDU"
(The quotes really aren't necessary anymore, they are there for
upward compatibility with the Jan 85 pathalias, so you can just
as well use this.)
	ucbvax = .Berkeley.EDU

Note that this applies to all domains, not to LAN names.  (If you
are putting your LAN name on the map, chances are something is wrong;
unless there is a good reason for the whole world to know the name
of every PC on your LAN as an unqualified name, please take your
LANs off the published map and put them into your private additions
used as input to pathalias.)  For the most part, you'll know it's a
domain because it ends in COM, EDU, GOV, or the 2 letter abbreviation
of a country.  Other domains, which are being phased out, end in ARPA,
CSNET, BITNET, UUCP, CDN, and so on - names of actual networks.

The version of smail to be posted soon supports both dotted and undotted
domains, but it prefers dotted domains.  So, while things won't fall
apart if the whole world doesn't convert at once, it's still a good idea
to send us your latest map, with dots in any domain names.  We'll take
care of the u.Path.* files ourselves.

If you are running software that uses domain names that doesn't know
about dots, you'll need to make some provision.  (The change to smail
was simple, just check with a dot before checking without a dot, for
each level in the domain tree.)

Even if you don't have any domain names in your entry, this is a good
time to send us an updated map entry if you haven't sent one in recently.
