IP Address Parsing and Manipulation

Functions

Function	Description
`ip_from_octets`	Build IP from 4 octets.
`ip_octet`	Get octet n (0=first/MSB, 3=last/LSB).
`ip_parse`	Parse “a.b.c.d” string to integer.
`ip_write_int`	Internal: write integer digits to buffer, return length.
`ip_format`	Format integer IP to “a.b.c.d” string. Returns length.
`ip_is_private`	Is this a private (RFC 1918) address?
`ip_is_loopback`	Is this a loopback address?
`ip_is_multicast`	Is this a multicast address?
`ip_mask`	Internal: create subnet mask from prefix length.
`ip_network`	Network address for addr/prefix.
`ip_broadcast`	Broadcast address for addr/prefix.
`ip_in_subnet`	Check if addr is within network/prefix.
`ip_to_sockaddr`	Write struct sockaddr_in (16 bytes) to dst for use with connect/bind. AF_INET…

fn ip_from_octets(a: i64, b: i64, c: i64, d: i64) -> i64

Build IP from 4 octets.

fn ip_octet(addr: i64, n: i64) -> i64

fn ip_parse(src: &i8, len: i64) -> i64

Parse “a.b.c.d” string to integer.

fn ip_write_int(val: i64, dst: &i8, off: i64) -> i64

Internal: write integer digits to buffer, return length.
