Because being able to have different services on different hosts / providers is a good thing. Your SIP service is handled on one machine. You mail on a different machine. HTTP on a third and ftp on a forth. I don’t know what new services are going to be dreamed up. I do know that some of them are not going to wanted to be on the same machine that is serving HTTP, or SMTP, or SUBMISSION or … HTTP is actually the odd man out here. Lots of other protocols have taken up SRV or used other mechanisms to be able to direct traffic to particular servers. > Matthijs > > >> Ray >> _______________________________________________ >> DNSOP mailing list >> DNSOP@ietf.org >> https://www.ietf.org/mailman/listinfo/dnsop > > _______________________________________________ > DNSOP mailing list > DNSOP@ietf.org > https://www.ietf.org/mailman/listinfo/dnsop -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: ma...@isc.org _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
