Create IpAddress from a string notation or a Long value

ip1.equals(ip2) // true

IpNetwork compares the subnets (or lower and upper boundaries) rather than their individual IP address values. That's why following example returns true.
IpNetwork("192.0.2.0/24") == IpNetwork("192.0.2.112/24") // trueYou can exactly specify which portion of each IpNetwork you’d like to compare.
IpNetwork("192.0.2.0/24").ip == IpNetwork("192.0.2.112/24").ip // false
