IPv4 is the IP protocol version that is running most of today’s internet.

Addresses in IPv4 are described using 4 bytes, giving it a maximum range of a little over 4 billion available addresses. That is far from enough for today’s needs. It is also one of the main reasons for the need of NAT devices.

WebRTC supports both IPv4 and IPv6.
