I'll explain a little elaborated so that i can explain myself clearly. I was facing problem when launching GTA5 Online, there was a problem of authentication, so i had to use VPN every time. Yesterday i found out that Rockstar servers might have blocked the IPv4 of my ISP(Jiofiber from India) thats why i face that problem. I found a solution online, logged in into my Jiofiber Router's setting, went to WAN and changed the default IPv4 DNS of my ISP to google's DNS i.e 8.8.8.8 and 8.8.4.4! Now the problem i was facing was resolved, i was wondering if i should also put Google's DNS in my Network Adapters also? (Control Panel\Network and Internet\Network Connections)... or changing the DNS from any of the two i have mentioned gets the things done? Please give me few more tips, like Is using Google DNS safe as my Dafault ISP's DNS? Is there any danger? Can anyone steal my banking passwords etc? Should i also Change my IPv6 to Google's IPv6? What changes would switching to Google's IPv6 do?
