Personally I've found them useful at different times in different places but that's some hair-splitting neither of us is particularly interested in. > just because you own an A RR doesn't make you a hostname. > > just because you're pointed to by an MX RR doesn't make you a mailname. > > (what a relief to finally be able to say that.) At the risk of hair-splitting that I've already disclaimed, I'll halfway agree (a host that doesn't accept connections arguably isn't a host) and halfway disagree (the target of an MX must be a valid hostname). To ensure that this thread dies now, I'll point out that I categorized some of this as part of my second stab at the great white whale of i18n DNS [see http://www.ehsco.com/misc/I-Ds/draft-hall-dns-datatypes-00.txt which ensures nobody comes back] -- Eric A.
