Hi all,

Please let me know if there is some feature in any of the versions of BIND, by which it switches to TCP when it detects spoofed replies. I am aware that BIND uses UDP for all its query / response and TCP for zone transfers.
I know of no such feature. What do you mean by "spoofed" anyway? How would you expect named to detect "spoofing", and is that its job?

One exception to your "awareness" is that TCP is used as a fallback if the initial UDP response signals truncation.
