Dear, I have a BIND 9.10 public server and I have delegated some public
When I test these domains with the EDNS tool offered in the DNS Flag Day
webpage, the test was wrong wit just UDP/53 port opened to Internet.
After that, when I opened also TCP/53 port, the test was succesful.
Please can you explain me the reason I have to open TCP/53 port to Internet
from February 1st to the future???
Really thanks, regards.
