I have another (sigh) question about domains. I've been told that in order to use domains, I would have to register my site with an Internet site (uunet, for example). I don't understand this. Why can't I just add a domain address to my uucp map entry and use it anyway, without registering? I realize that mail will not be able to traverse into the realm of Internet. But isn't it the eventual goal to have everyone using domains anyway? Why can't I just add the entry to my map (assuming, of course, I don't care about Internet)? Can anyone explain this?

The problem is that, if you don't register a domain name with the NIC, then all you've done by changing your UUCP map entry is to change the name by which you're referred in UUCP addressing, which is to say that you've done yourself no good at all: Given that people can already reach you via the existing UUCP registry, you gain nothing by changing (adding what amount to aliases for) that name. The win of registering a domain name properly is that anyone anywhere can then reach you. And they don't have to know _how_ you're being reached, since domain addresses imply no routing or transport. I suppose you _could_ just add a domain name to your map entry, if you could get it past your regional map coordinator (which I doubt). But it seems awfully pointless. --karl

Curious that you should ask this just now . . . we've recently found a few sites doing just that in mi.us and mi.org. You might appreciate knowing what happened. Mail started showing up at some of the central distribution points for the michigan domains with no obvious place to send it. After looking it over and seeing no obvious way to get it out, it was returned to sender. Result 1: some of your mail won't get delivered, and the postmasters who are stuck with it will become irritated. We then found some sites that put the addresses in their uucp maps but never registered them on the internet. Pure internet sites (which don't necessarily use the map if it looks like a valid internet address) cannot mail to that address. Result 2: some of your mail won't get delivered, and the postmasters who are stuck with it will become angry. We then found some sites that even sent in the registration papers saying their mail should be forwarded thru specific internet sites, but they neglected to ask those sites if it was OK. The agencies in charge of the MX records assumed (reasonably) that the registering site had permission to use the internet site, and suddenly that internet site was hit with unexpected and undeliverable mail. Result 3: some of your mail won't get delivered, and the postmasters who are stuck with it will become very angry, along with the NIC and ISI. We then got out the rakes, shovels, and implements of destruction and did our damnedest to ensure this will never happen again. The people who misused the registrations are going to have a damned hard time getting more than the absolute minimum co-operation from the major local mail relay sites. Result 4: you will have to register anyway, after recieving a metaphoric black eye in the local email community. Other states may be different, but in Michigan I'd suggest you register.

And when someone sends mail to jessea@dynasys.com via uunet and the MX lookup fails, your mail will be returned to sender - address unknown. You can't do this - it's like changing your mailing address without moving ( example: deciding you don't like Tennesee and declaring that Memphis is now part of California. Mail to Jesse in Memphis Ca. will probably be returned to sender [if it's not simply lost] ). I see that you're a uunet.uu.net customer. They can register you for real at a nominal fee ( worth it to avoid the paperwork ). -- Ed Clarke | Happiness, n.

In article <72@dynasys.UUCP> jessea@dynasys.UUCP (Jesse W. Asher) asks
why he can't just make up a domain, put it in his uucp map entry, and
then use it without going through the formal registration period.
Well, there are a number of reasons. The first is that large numbers
of sites out there (ours included) use the nameservers to resolve
addresses. If you made up your own domain (say, dynasys.com), and
started using it, all of the sites that use nameservers, or that
forward their domain-ized mail to sites with nameservers, would
suddenly be unable to communicate with your site. For instance, if I
tried to send mail to someone with an address like that, it would come
back with an "unknown domain" error. The number of sites in this
category is large, and growing larger everyday; it also includes most
"major" sites on the net. We don't use the uucp maps to send mail to
sites with proper domain names. I suspect you wouldn't even be able to
get mail through uunet, since I bet the mailer there does exactly the
same thing as ours.
A second good reason is collisions. Maybe you're the only dynasys in
the world. Maybe not. If you don't have a central authority that
tracks names and ensures there are no collisions, you may suddenly
find that some other place out there is also going by the name
"dynasys.com" -- and they've registered their name so you're out of
luck.
A third reason is that I bet the folks maintaining the maps won't take
a domain name in a map entry unless it is registered somewhere.
If you're going to do it, do it right. Get a properly registered domain.

Yea? Well who's going to hold your MX record? And who's going to forward
your mail?

uunet customers can get registered for no extra fee. Non-uunet
customers can be registered by uunet for either $30 or $35. ($30 is
the one-month uunet "membership fee" or whatever it's called.)

Simple.. For the domain system to be effective everybody must agree on the names. This pretty much means a fairly centralized control of the names. Earlier a totally centralized control was attempted, but this was found to be unworkable. The turn around time to get entries into the Official File became horrendous and, I'm sure, the network bandwidth in transferring the Official File from the Official Site to hither and yon was driving the Official Site batty. So now we have a distributed control of the naming tree. In order to establish a domain name at some level, say .com, you talk to the authority at that level. In this case hostmaster@nic.ddn.mil. You tell he guy and/or gal you want this name, say mmdf.com. And they mumble for awhile and decide you're ok and let you have it. That's the hard part, now whenever you want to add an entry into mmdf.com, say davids.mmdf.com, you just add a record to the nameserver servicing your domain. For instance this amiga sitting at the other end of the table from my Unix PC (the Unix PC is davids.mmdf.com) may well soon become known as amy.mmdf.com. Right now amy is known as amy.funky-do-do. That's because I was installing UUCP & mail & Usenet on it, the software asked for a domain name and I knew I'd better not use one of the legal domain suffixes. So I made one up. Weird sh*t, huh? :-) All that'll be required is telling the guy at rutgers who takes care of my domain file to add in another MX record... -- <- David Herron; an MMDF guy <david@ms.uky.edu> <- ska: David le casse\*' {rutgers,uunet}!ukma!david, david@UKMA.BITNET <- <- Now arrived at a nameserver near you: david@davids.mmdf.com
