format error
 

Hi,
I am using BIND 9.2.4 on LINUX 2.6.9. I am facing the following issue:
The domain name is set to testdns.com and when i update my host name as test, the update goes through fine to the DDNS server.
But when my host name reaches 64 characters, the server sends the "Format Error" response code.
I know domain name can be upto 256 bytes, but is 63 limiting factor for the host name?

Any help is appreciated.

Thanks in advance,
nsvora
