# > when did the ietf community start ruling by law rather than leading by # > recommendations? can't we just say "any application or library which # > does DNS lookups to translate presentation-layer endpoint identifiers # > into network-layer endpoint identifiers should take care to avoid doing # > DNS lookups for presentation-layer content which is syntactically valid # > as an IPv4 or IPv6 host name"? # # Except that we've now created a class of names that are OK to register, and # OK to populate in the DNS, but some applications will never be able to look # up.... that's kind of bizarre. then make a recommendation that IANA not allocate such names as toplevels? (what people choose to do further down the tree is not up to us to decide.) # I think the "don't register numeric TLDs" is a recommendation too, in the # sense that everything the IETF produces for external consumption is. And a # simpler one. right. # > (that's from bind4's gethnamaddr.c file, similar stuff is in bind8/bind9.) # # entirely tangential, but illustrates something, I think.... # # this line of code is mostly responsible for the widely held but erroneous # belief that hta@129.241.1.99 is a valid email address. worse than that: it's valid for some people some of the time. the logic in gethostbyname() was put there because applications could not be depended upon to say "if it's a valid address, use it, else look it up as a hostname" and so gethostbyname() became a dual-purpose function. probably it would've been better to return an error on the basis of non-RFC952-compliance. (who knew?) # hta@[129.241.1.99] is a valid email address. hta@129.241.1.99 isn't. # Some mailers get it right, some don't. really? i know that mailnames used to have to start with non-numeric, but 3com.com asked for a change and got it. do the current (2821/2822) railroad diagrams really say that 129.241.1.99 is not a valid mailname? -- to unsubscribe send a message to namedroppers-request@ops.ietf.org with the word 'unsubscribe' in a single line as the message text body. archive: <http://ops.ietf.org/lists/namedroppers/>
