In fact the test check for a '-' at the beginning or at the end of a label as suggested in the grammar of 1035.
That section of 1035 is a source of great confusion. Note that the text preceding the parsing rules says: "The following syntax will result in fewer problems with many applications that use domain names (e.g., mail, TELNET)." It doesn't say that the syntax rules are mandatory. In fact, elsewhere: # Because these files are text files several special encodings are # necessary to allow arbitrary data to be loaded. In particular: # # \X where X is any character other than a digit (0-9), is # used to quote that character so that its special meaning # does not apply. For example, "\." can be used to place # a dot character in a label. # # \DDD where each D is a digit is the octet corresponding to # the decimal number described by DDD. The resulting # octet is assumed to be text and is not checked for # special meaning. So, arbitrary octet values are allowed, but isn't 8-bit clean because of the upper==lower case rules.
I don't think there are many anycast server for now, but the heuristic used to determine the subnet make it already a policy issue :(
And I fear that the rise of anycast server will make it really difficult to check the consistency of the different server for a zone.
I've already been slapped by our beloved WG chair (Jim) for the same comment when I accused him of placing both name servers for an ENUM experiment on one LAN. He muttered 'they're anycasted...'
We could provide different list of test, where the degree of completeness increase.
At least a flag to trim back the tests...
These tests are only marked as 'Warning', due to the fact that if you really know what you are doing you could want to go beyond the recommanded values.
Peter mentioned that there is a RIPE document behind this. I wasn't aware of that. (As an aside, there was a short post meeting discussion about where would we publish operations documents - as in within what venue?) -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Edward Lewis +1-703-227-9854 ARIN Research Engineer Your office is *not* a reality-based sit-com TV show.
