RFC 1033 is not even mentioned RFC 1035 is recommended RFC 2181 is elective draft-oscarsson-i18ndns-00 is a new draft this year, (not mentioned) I, too, hope that the papers written by Randy Bush, Dan Oscarsson and others will someday (soon!) become required internet standards. I tip my hat (if I had one) off to them. However, I think we can very safely say that (at least on August 7th, 2000) the '_' character is not a "legal" character in a domain name. (This is actually a FAQ from comp.protocols.tcp-ip.domains, so I apologize for stating the already stated.) -Paul.
