doering@kodak.UUCP (Paul F. Doering) (05/17/89)
Distribution: na Organization: Kodak Research, Rochester NY What is the common practice in connecting to Internet when a commercial organization has geographically-dispersed research sites? Does each research site connect independently to its closest consortium (NYSERnet, NEARnet, etc)? Is there a domain-name problem? Can each of the company's research sites share the parent company's domain-name, even if widely separated, as westcoast.poobarcorp.com, eastcost.poobarcorp.com, sunbelt.poobarcorp.com...., even if joining several consortia means that there is no common gateway machine? Please reply or ask clarifiaction of the question by e-mail. Thanks. -- ========================= ====================================== Paul Doering (for self) Man will never arrive, rochester!kodak!doering man will be always on the way. ========================= =============== -Carl Sandburg =======

Well, I tried mailing back to you but sending to doering@kodak.UUCP (Paul F. Doering) resulted in the following bounce so everybody gets to read this deathless prose while at the same time scratching their head over why the Received: lines don't say it went to Korea while at the same time the From: in the message says it *DID* come from Korea.

I know that lots of companies have their own internal networks which they use for internal business.

I know that DEC's machines are connected to Cypress, BARRnet and some NSFnet in the DC area -- at least. DECWRL is on Cypress & BARRnet and the decuac machine is in the DC area. I don't see anything stopping you from joining more than one consortium.

No problem here at all! You could, for instance, declare a kodak.com gateway and for any sub-domains which you want explicit gateways for declare them as you need... all with MX records or usenet entries or whatever. -- <- David Herron; an MMDF guy <david@ms.uky.edu> <- ska: David le casse\*' {rutgers,uunet}!ukma!david, david@UKMA.BITNET <- By all accounts, Cyprus (or was it Crete?) was covered with trees at one time <- -- Until they discovered Bronze -- <- David Herron; an MMDF guy <david@ms.uky.edu> <- ska: David le casse\*' {rutgers,uunet}!ukma!david, david@UKMA.BITNET <- By all accounts, Cyprus (or was it Crete?) was covered with trees at one time <- -- Until they discovered Bronze

Paul F. Doering of Kodak asks about having multiple research sites connected to different parts of the Internet. This can be done easily. In order to make sense of this, it is necessary to understand that numeric internet addresses and domain names are completely separate things. Each research facility would apply for a separate internet network number. The company as a whole would apply for a domain name, and would have complete freedom to assign names under that. In general, the network number is related to the physical connection of the network and the domain name is related to the organizational or political hierarchy of the company. It is possible to have two different workstations in the same domain but in geographically separate areas. Example name server entries: $ORIGIN plastics.poobarcorp.com. hosta IN A 193.001.001.025 hostb IN A 193.001.002.037 In this example, class C networks 193.001.001.x and 193.001.002.x may be half a continent apart, but the routing tables maintained by the Internet will allow packets to be routed properly to each of them. The fact that they have names within the same subdomain of poobarcorp.com has no relevance whatsoever. It is also possible for a company to apply for a single class-B or class-A network number, but it is that company's responsibility to provide complete connectivity between all parts of that network internally. It is not possible to have different pieces of the same network connected to the Internet in different places. I have only addressed the technical issues here. The NSFnet or regional network administrations probably have rules applying to this situation. -- Bob Hoffman, N3CVL {allegra, bellcore, cadre, idis, psuvax1}!pitt!hoffman Pitt Computer Science hoffman@vax.cs.pittsburgh.edu
