Applications for IP-in-IP

IP-in-IP encapsulation is simple and robust. It is useful for connecting IPv4 networks that otherwise would not be able to communicate; however, it has some limitations:

  • IP-in-IP encapsulation does not support broadcast traffic.
  • IP-in-IP encapsulation does not support IPv6 traffic.

For forwarding this kind of traffic, GRE may be more appropriate.
