```

## Usage

```crystal

require "ipaddr"

```

# => #

ipv6 = IPAddr.new("2001:db8::deca:face")

# => #

```

### IPv4 compatible/mapped IPv6 address

```crystal

v4compat = ipv4.to_ipv4_compat

# => #

v4mapped = ipv4.to_ipv4_mapped

# => #

v4compat.native_ipv4

# => #

v4mapped.native_ipv4

# => #

```

### Network address

```crystal

nw  = IPAddr::NetworkAddr.new(ipv4, 16)

# => #

nw2 = IPAddr::NetworkAddr.new("2001:db8::beaf:cafe", 120)

# => #

nw3 = IPAddr::NetworkAddr.new("192.168.20.2/255.255.255.0")

# => #

nw4 = IPAddr::NetworkAddr.new("2001:db8::beaf:cafe/120")
