All quiet in the IPv4 Internet?

Instead of using fd with a RNG, you should follow the RFC...

SixxS even runs a registry for ULA prefixes: https://www.sixxs.net/tools/grh/ula/

Put in your MAC address, get back a ULA. Then register it so that in the future if someone happens to have the same mac address you don't accidentally use the ULA.

I'm following the RFC: "Locally assigned Global IDs MUST be generated with a pseudo-random algorithm consistent with [RFC 4086]. Section 3.2.2 describes a suggested algorithm."

I happen to be of the opinion that /dev/urandom is more likely to comply with RFC 4086 than the suggested algorithm, but I may have an unfairly low opinion of the distribution of timestamps and MAC addresses.
