@DarkNate , sorry for replying late, how do I find those expanded ip’s which are near me (lowest ping). For single isp with google server is the below example work?
/ip dns
set allow-remote-requests=yes query-server-timeout=100ms query-total-timeout=5s
servers=8.8.8.8,8.8.4.4,2001:4860:4860::8888,????:????:????::8844
use-doh-server=https://dns.google/dns-query verify-doh-cert=yes
/ip dns static
add address=104.16.248.249 name=cloudflare-dns.com type=A
add address=104.16.249.249 name=cloudflare-dns.com type=A
/ip route
add dst-address=0.0.0.0/0 gateway=pppoe-out1 routing-mark=to_ISP1 check-gateway=ping
add dst-address=8.8.8.8 gateway=pppoe-out1 scope=10
add distance=1 gateway=8.8.8.8 routing-mark=to_ISP1 check-gateway=ping
add distance=2 gateway=8.8.4.4 routing-mark=to_ISP1 check-gateway=ping
