What is an IPv4 address?

An IPv4 address is a 32-bit numerical label assigned to devices connected to a computer network, expressed as four octets separated by dots (e.g. 192.168.1.1).

What is a private IP address?

Private IP addresses (RFC 1918) are reserved for use inside local home or corporate networks and cannot be directly routed on the public internet.

What is the difference between IPv4 and IPv6?

IPv4 uses 32-bit addresses supporting ~4.3 billion addresses, whereas IPv6 uses 128-bit addresses supporting 340 undecillion addresses.

Is my IP address checked on a server?

No, all format analysis and binary calculations execute entirely client-side in your browser.
