Class IPAddressParser

java.lang.Object

org.apache.commons.ssl.util.IPAddressParser

public class IPAddressParser
extends Object

Parses String representations of IPv4 and IPv6 addresses, and converts them to byte[]. Returns null if the supplied String is not a valid IP address.

IPv6 addresses are allowed to include square brackets (e.g., "[::a:b:c:d]"), but IPv4 addresses are not. This is to help in situation where an IPv6 literal address is encoded directly inside a URL (the square brackets allow the web client to separate the IPv6 address from its port, since the colon character is overloaded in that context).
