Hi.
when not connected to netbird, the MacOS is using the regular laptop DNS and all is well.
but once connected to netbird (and IPv6 is enabled on the MAC), any requests to external resources are automatically delayed by 30 seconds.
it seems that if i do nslookup i always get the correct IP but using netbird i can see also an additional line for rdata_46).
if i run:
sudo networksetup -setv6off Ethernet
sudo networksetup -setv6off Wi-Fi

it disables the IPv6 and works right away
so it seems that the internal netbird DNS resolver is trying to query via IPv6
