Socket::IPAddress
struct Socket::IPAddress
Overview
IP address representation.
Holds a binary representation of an IP address, either translated from a String, or directly received from an opened connection (e.g. Socket#local_address, Socket#receive).
Example:
Socket::IPAddress.new("127.0.0.1", 8080)
Socket::IPAddress.new("fe80::2ab2:bdff:fe59:8e2c", 1234) IPAddress won't resolve domains, including localhost. If you must resolve an IP, or don't know whether a String constains an IP or a domain name, you should use Addrinfo.resolve instead.

socket/address.crClass Method Summary
- .from(sockaddr : Pointer(LibC::Sockaddr), addrlen) : IPAddress
Creates an
IPAddressfrom the internal OS representation. - .new(address : String, port : Int32)

Instance Method Summary
- #==(other : IPAddress)
- #address
Returns a
Stringrepresentation of the IP address. - #port : Int32
- #to_s(io)

Class Method Detail
def self.from(sockaddr : Pointer(LibC::Sockaddr), addrlen) : IPAddressSource
Creates an IPAddress from the internal OS representation. Supports both INET and INET6 families.
Instance Method Detail
def addressSource
Returns a String representation of the IP address.
Example:
ip_address = socket.remote_address ip_address.address # => "127.0.0.1"
