Use google dns will help to avoid tons of weird issues when browsing the internet, if not all (Some dirty isp even sniff and change the dns response, very nasty, simply change to google dns won’t do much help in this case).

Beyond ipv4 dns, they even have a ipv6 version of the addresses, so I keep a quick note here for quick reference later:
ipv4 version:
8.8.8.8
8.8.4.4

ipv6 version:
2001:4860:4860::8888
2001:4860:4860::8844
