I read the following statement in rfc1996:

3.4. The transport protocol used for a NOTIFY transaction will be UDP
unless the master has reason to believe that TCP is necessary; for
example, if a firewall has been installed between master and slave,
and only TCP has been allowed; or, if the changed RR is too large to
fit in a UDP/DNS datagram.

Now since this is exactly what I need so I wonder if it is possible to make
the master believe that it is necessary to use TCP?

Thanks in advance,
