Jen: support engineers who need explanations on ping, would need more detailed explanations on how to change DNS settings.
- Section 5 You provide detailed instruction on how to run ping, but then saying just 'check DNS settings' and even 'configure different servers' - support engineers who need explanations on ping, would need more detailed explanations on how to change DNS settings.
"If IPv4 is working but the page is unavaliable' - I'd assume that an engineer could not tell if 'IPv4 is working'. So IMHO we shall just say that if site is unreachange - troubleshoot as any other 'I can not open this page' v4-only case. If we believe that troubleshooting such case is in scope of this document, I'd suggest to include traceroute as a troubleshooting step.
