addressStringToInet
(String addr) Convert an IPv4 or IPv6 textual representation into an InetAddress.abstract boolean
contains
(InetAddress inetAddress) Compares the given InetAddress against the CIDR and returns true if the ip is in the subnet-ip-range and false if not.boolean

getIpV4FromIpV6
(Inet6Address address) Compute a byte representation of IpV4 from a IpV6static byte[]
getIpV6FromIpV4
(Inet4Address address) Compute a byte representation of IpV6 from a IpV4int

hashCode
public int hashCode() -
addressStringToInet
Convert an IPv4 or IPv6 textual representation into an InetAddress.- Returns:
- the created InetAddress
- Throws:
UnknownHostException
