possible bug report (malformed?) internet addresses - FreeBSD

$ ping "mr-chips-.deviantart.com" ping: cannot resolve mr-chips-.deviantart.com: Unknown server error $ ping "etc-etc-etc.deviantart.com" PING etc-etc-etc.deviantart.com (69.28.181.43): 56 data bytes 64 bytes from 69.28.181.43: icmp_seq=0 ttl=50 time=108.127 ms At first it may seem logical to point the blame to the server, after noting "Unknown server error," however, I am perfectly able to connect to this address on a Windows machine. The problem is reproducible with any address which has a "-" before a "." I am not sure where the problem lies, it is obviously not just within 'ping,' as I first noticed this problem within firefox/mozilla....

    Almost forgot.

    (I haven't cvsup'd and re-built in a little while.. maybe one of you
    who have could verify the problem still exists..)

    Interesting. Host can look it up:
    bash-2.05b$ host mr-chips-.deviantart.com
    mr-chips-.deviantart.com has address 69.28.181.43

    But the host name is itself invalid. From RFC 1035:

    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.

    My guess is Windows is actually munging it, when it would be better to
    return an error.
