In the list of nameservers in resolv.conf, can I use different nameservers (one from ISP, one from Google, etc..) in each line or does it all have to be from same source?
nameserver 18.104.22.168 <-- ISP nameserver 22.214.171.124 <-- Google nameserver 126.96.36.199 <--- OpenNIC
Is mixing the nameserver sources normal or is it advisable to stick to only 1 source with 2 or 3 ip addresses from them?
I am asking this cuz all docs and examples I've seen only shows ip addresses from 1 source either Google, ISP, or other third-parties. I havent seen 1 that has mixed nameservers and wondering if that's normal.
