your answer to "Actually my situation is a bit strange . But as

nonsense ? :O I use from tons of years and even on single computers

that has no meaning in any language, but if you want to play the expierience card i play mine: professional dns/network admin for some hundret domains including write named backends....

*_forwarders are not a needed stuff even for caching even for authoritative_*

use only TLD but if port 53 is closed you have no "normal" way to gain access to root TLD DNS engines

and *hence* he wants to forward the traffic to a dns server on port 443 *which has access and can do recursion* - so just stop it - none of your responses is helpful for anybody, it's just noise

I read so well your answer and wasn't an answer to you


in all case ,                who said I can't use port 53 if blocked ? 😲         are many ways       without a VPN that usually is a paid service or a company service for who have it.


In all case even VPN even 443 is open, can be dropped 😲 ... pass 443 (browser) but not VPN.


In all case here wasn't a discussion on hacking or bypassing protections or limitations! So I'll quit any other answer on this topic over the real question.

jesus fix your quoting style and english - non of your responses was in
any case helpful and other than you people with expierience guess what
the reason for somenon.default configs likely is

your answer to "Actually my situation is a bit strange . But as

normal ports 53 tcp/udp" coming with "port 53 is only open directed to
forwarders" and "I think u should read how DNS works, TLD and so on

when the ISP of his upstream internet connection mangles traffic on port
53 and you still recommend drop forwarders and use port 53 who is the
one which don't undertand DNS or the topic

can you please refrain from answering to each and every post in a thread
you obvisouly don't understand?

even on hotel ......... why not to use a BIND on unix or window on ur box u r using ?

did you read what i repsoned and too and did you try to understand my
answer?

a default bind with recursion won't work when it can't connect to the
world in case it is redirected to a hotel nameserver and when you can
only connect to 80/443, well then your BIND on the box you are using may
use a nameserver you own in the web running on 443

1. who runs DNS servers on port 443?

likely people which where bitten by hotel access points where 53 is
catched to a internal nameserver and outgoing only 80/443 are possible,
the same reason many people have a VPN server on 443
