Represent address as raw bytes

Encode or decode an ip_address as a list of raw bytes.

Usage

ip_to_bytes(x)

bytes_to_ip(x)

Arguments

x

• ip_to_bytes(): An ip_address vector

• bytes_to_ip(): A list of raw vectors or a blob::blob object

Value

• ip_to_bytes(): A list of raw vectors

• bytes_to_ip(): An ip_address vector

Details

The bytes are stored in network order (also known as big-endian order), which is part of the IP standard.

IPv4 addresses use 4 bytes, IPv6 addresses use 16 bytes, and missing values are encoded as NULL.

See also

Use blob::as_blob() to cast result to a blob object

Other address representations: ip_to_binary(), ip_to_hex(), ip_to_integer()

Examples

x <- ip_address(c("192.168.0.1", "2001:db8::8a2e:370:7334", NA))
