Scala库为代表的IPv4地址，网络，和相关概念

scala-ipv4 is a Scala library for IPv4 related concepts such as IP addresses, network masks, address pools, etc. Key Concepts IpAddress IpAddress represents an IPv4 address. val address = new IpAddress("192.168.0.1") IpAddress can be used to make calculations on IP addresses, such as finding the next address. val address = new IpAddress("192.168.0.1")val next = address + 1println(next == new IpAddress("192.168.0.2")) // prints true IpAddressRange IpAddressRange represents a continuous range of consecutive addresses. val range = new IpAddressRange(new IpAddress("192.168.0.1"), new IpAddress("192.168.0.5"))println(range.contains(new IpAddress("192.168.0.3")) // prints true IpNetworkMask IpNetworkMask represents a network mask, to be used in an IpNetwork. ``` val mask1 = new IpN
