How can I find out which would be the best DNS for Xbox online? Is there a DNS ping tool or something? I have random spikes online.
Hello Infected: "Best" is really too vague. Many start with IP = 8.8.8.8/8.8.4.4 (IPv4) and then later improve upon Google's Nameserver. If you are looking for speed only, run Steve Gibson's https://www.grc.com/dns/benchmark.htm. Most frequently though, the fastest is with your own ISP. If you are looking for privacy/safety, that is an entirely different question. https://www.opendns.com/about/innovations/dnscrypt/ Will you be entering the prospective DNS Nameserver IP addresses in the Xbox or in a router/gateway? HTH
No one can suggest which DNS is best for you for whatever purpose. Gibson's DNSbench does report on latency. Another good tool is Network Latency Tool by Nirsoft.
