This is a change in the bind code; it now enforces standards which everyone is already required to comply with, but which they frequently do not. The cannonical name of "www.mcafee.com" is "sc_axp2.mcafee.com"... According to RFC1035: | | <domain> ::=<subdomain> | " " | <subdomain> ::=<label> | <subdomain> "." <label> | <label> ::=<letter> [ [ <ldh-str> ] <let-dig> ] | <ldh-str> ::=<let-dig-hyp> | <let-dig-hyp> <ldh-str> | <let-dig-hyp> ::=<let-dig> | "-" | <let-dig> ::=<letter> | <digit> | <letter> ::=any one of the 52 alphabetic characters A through Z | in upper case and a through z in lower case | <digit> ::=any one of the ten digits 0 through 9 | | Note that while upper and lower case letters are allowed in domain | names, no significance is attached to the case. That is, two names | with the same spelling but different case are to be treated as if | identical. | | The labels must follow the rules for ARPANET host names. They must | start with a letter, end with a letter or digit, and have as interior | characters only letters, digits, and hyphen. There are also some | restrictions on the length. Labels must be 63 characters or less. See also RFC1706, RFC1995, and RFC1996. Please notify McAfee that they are using an illegal host name. The lowest impact would probably be to change "sc_axp2.mcafee.com" to "sc-axp2.mcafee.com".
