Hi everyone out there. I am wondering (mainly just out of curiosity)
about the implementation and usage record of source routing in the early
Internet. The IPv4 spec (starting with IEN 80) came to include it
eventually, but my impression is that while people *thought* it would be
important, in reality no one cared too much and it wasn't used much.

My question: have people actually been using it for purposes other than
spoofing attacks? What about routing debugging? And, load balancing?

Plus, how widespread did it become in gateways/routers before security
concerns rendered it a complete no-go?

Thanks for your recounts and takes.
