255 is the wire format limit not the presentation format limit :-) If you don't have any escaped characters, the presentation format (including terminating dot) is one shorter than the wire format because the wire format has a length byte before each label plus a terminator at the end, whereas the presentation format doesn't have a dot at the start. With escaping the presentation format of a name can be 1004 characters. (254 - 4) * 4 + 4 Tony. -- f.anthony.n.finch <d...@dotat.at> http://dotat.at/ Trafalgar: West or northwest 4 or 5, increasing 6 at times. Slight at times in far southeast, otherwise moderate, occasionally rough at first in north. Showers in north. Good. _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
