Every now and then... try this.
Today, I learned the shortest command which will determine if a ping from your machine can reach the Internet:
ping 1.1
This parses as 1.0.0.1, which thanks to Cloudflare, is now the IP address of an Internet-facing machine which responds to ICMP pings.
Oh, you can also use this trick to parse 10.0.0.x from `10.x` or 127.0.0.1 from `127.1`. It's just like IPv6's :: notation, except less explicit.
