The restriction on starting with a digit is virtually non-existent at this point. > How about underscores as per informational > rfc1035? Underscores are not valid in hostnames. If you are using underscores for names seen on the internet you should change them asap. One of many good reasons is that they will be used to differentiate the new SRV pseudo-hostnames. For those that want to argue that there is nothing cut in stone about not using underscores in hostnames, please don't bother. At minimum it's "current best practice," and it probably actually *is* codified in the RFC's, but that's a debate for another list.
