Binary to IP
Decode a 32-bit binary value or four binary octets back into an IPv4 address.
Either a 32-bit string or four 8-bit groups separated by dots.
Dotted-decimal IPv4.
Decode a 32-bit binary value into an IPv4 address. Inputs may be a single 32-bit string or four 8-bit groups separated by dots, which is how networking textbooks usually present the binary form.
Why use dotted binary?
Grouping by octet matches the structure of IPv4 addressing and makes mental conversion easier.
