IP Address Format Reference
IPv4 addresses are 32-bit integers typically written in dotted-decimal notation. The same address can be expressed as a decimal integer (useful in databases), hexadecimal (common in low-level network code), or binary (useful for understanding subnetting). IPv6 uses 128-bit addresses in hexadecimal groups with :: shorthand for runs of zeros.
