<div dir="ltr">Dear, I have a BIND 9.10 public server and I have delegated some public domains.
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>After that, when I opened also TCP/53 port, the test was succesful.</div>
<div><br>
</div>
<div>Please can you explain me the reason I have to open TCP/53 port to Internet from February 1st to the future???</div>
<div><br>
</div>
<div>Really thanks, regards.</div>
