Lost Internet NXDOMAIN?

Question

Domain Name System

I download a torrent at the maximum speed of the Internet, sometimes I can’t access the pages, writes nhdomain. My provider is Rostelecom via tp-link dsl, and when I downloaded via freedom, there was no problem, there was a dlink router

Answer 1

Option 1 - TPlink router can't cope with the load when downloading torrents.
Option 2 - your ISP is spoofing DNS requests, so the sites swear.
Option 3 - a problem with the DNS servers of the provider (but then the sites, in theory, would not open at all)
Solutions - change the DNS (in the PC settings) to free and normal ones, for example
1.1.1.1
1.0.0.1
If the problem is only with torrents - most likely option 1 is correct, the problem is in the router.

Answer 2

ADSL in router mode does not hold a large number of simultaneous connections well (NAT does not cope, you need to look at /proc/sys/net/ipv4/ip_conntrack_max) I
advise you to connect in bridge mode, because torrent clients create many connections
