When diagnosing networking problems, I ping to:
- My local IP
- My gateway IP
- An external IP
- An external domain name
Usually, when troubleshooting, the internet is unaccessible, then I need to remember an external IP address.
I need any (easy to remember) IP address. By example, google ip is 188.8.131.52. Cool, but it's hard to remember...
What external IP you use? Do you have an mnemonic external IP address, then will be easy to remember?
