ANSWERED AirVPN DNS 10.4.0.1 very slow compared to 1.1.1.1

Recommended Posts

When I change my manually-set DNS server from 10.4.0.1 (AirVPN) to 1.1.1.1 (Cloudflare), browsing gets significantly faster: I estimated ~5x..10x faster when opening up a new webpage in chrome, so from 'very slow' to 'instant'.
Any ideas - I like to use the AirVPN DNS server... ?

Info: Using Windows 10, connected to Matar

That's a DNS-over-TLS port. Is your pfSense instance using that by any chance, or is it just another port for plain unencrypted DNS?

DNSSEC validation is one thing, transferring DNS queries another. Guess I'll have to check myself. :D

Kinda in the same problem here; pasting resolve times; only changed DNS. My first check was Diversion under MerlinFW on AC86U, but whatever I did, delay was still there. Changed DNS from 10.4.0.1 to 9.9.9.9 and voila. Tested on servers: AT, DE, CZ, CH.

time nslookup cnn.com
Server: 10.4.0.1
Address 1: 10.4.0.1

Name: cnn.com
Address 1: 151.101.1.67
Address 2: 151.101.193.67
Address 3: 151.101.129.67
Address 4: 151.101.65.67
Address 5: 2a04:4e42:200::323
Address 6: 2a04:4e42::323
Address 7: 2a04:4e42:600::323
Address 8: 2a04:4e42:400::323
real 0m 46.91s
user 0m 0.00s
sys 0m 0.00s

time nslookup cnn.com
Server: 9.9.9.9
Address 1: 9.9.9.9 dns9.quad9.net

Name: cnn.com
Address 1: 151.101.129.67
Address 2: 151.101.65.67
Address 3: 151.101.1.67
Address 4: 151.101.193.67
Address 5: 2a04:4e42:200::323
Address 6: 2a04:4e42::323
Address 7: 2a04:4e42:600::323
Address 8: 2a04:4e42:400::323
real 0m 0.19s
user 0m 0.00s
sys 0m 0.00s


Any additional input is appreciated! I'm kinda stuck if I don't change DNS 😕

EDIT: Retested, after every change of DNS servers applied "killall -1 dnsmasq". Still getting between 30 and 50 sec of delay when using 10.4.0.1 . Quad9 stays in 0.2-3sec.

(I'm the one who posted the problem.)
I have tried to reproduce the problem of the slow DNS.
Good news: the problem has been resolved - I'm not sure what has changed, but the performance of the AirVPN DNS is excellent now.
* When browsing in Chrome, it 'feels' as fast as 1.1.1.1
* When running DNS Benchmark to measure the performance, the AirVPN DNSs are the fastest. See DNS Benchmark results below.
* When using "time nslookup", I typically see ~0.3..0.4 sec

$ time nslookup bbc.co.uk

We can be 95% sure OP did something he/she doesn't usually do. The whole DNS problem was a local thing to begin with. If it wasn't, people would've noticed and posted the obligatory "I have the same issue" follow-ups. And I'm writing about tens or even hundreds of them, spanning over three or four threads, not just one other. I linked a particularly hilarious issue where everyone was truly affected, and this showed. :)

If it resurfaces, be sure to reply.
