interesting network commands

## about network info

curl ifconfig.me
curl ipinfo.io
traceroute <domain_name>

Example:

traceroute to google.com (172.217.168.206), 64 hops max, 52 byte packets

This line indicates the start of the traceroute to google.com. The IP address 172.217.168.206 is the resolved address for google.com. "64 hops max" means it will trace the route up to a maximum of 64 network devices (routers, switches, etc.) along the path. "52 byte packets" refers to the size of the test packets being sent.

Each subsequent line represents a “hop” along the path from your computer to the destination.

Asterisks * * * indicate that a hop did not respond within a certain time frame. This could be due to various reasons, such as firewalls blocking ICMP (the protocol used by traceroute), or packet loss.
