The value is tested against the rules at http://en.wikipedia.org/wiki/Hostname#Restrictions_on_valid_host_names
- At least two period-delimited segments
- Cannot start or end with a period
- Each segment must be between 1 and 63 characters
- The entire thing is no greater than 255 characters
- Valid characters are 'a' to 'z', 'A' to 'Z', '0' to '9', and hyphen (-)
- Labels cannot start or end with a hyphen
- The last segment must be a support top-level domains (and there are a LOT of strange ones)
