Hi, <http://tools.ietf.org/html/draft-ellermann-news-nntp-uri#section-8.2> proposes the registration of an nntp.uri.arpa NAPTR: | This section contains the [RFC3405] template for the registration of | the 'nntp' URI scheme with the Dynamic Delegation Discovery System. | | Key: nntp | Authority: RFCXXXX | Record: | nntp IN NAPTR 0 0 "" "" "!^nntp://([^/?#]*@)?([^:/?#]*).*$!\\2!i" . I hope that's as it should be. There's a small difference from the similar existing 'http' and 'ftp' records, noted in the "document history" of the draft: | If that record is correct the existing ftp.uri.arpa | and "http.uri.arpa" records could be updated, apparently they | don't remove the optional <userinfo> at the moment. For comparison the current ftp.uri.arpa and http.uri.arpa NAPTRs: | ftp IN NAPTR 0 0 "" "" "!^ftp://([^:/?#]*).*$!\\1!i" . | http IN NAPTR 0 0 "" "" "!^http://([^:/?#]*).*$!\\1!i" . Frank
