Look at that fried ethernet cable, Morty!

I love Mikrotik. Just fucking love them. I also love my residential fiber service. Small company. Synchronous 125M service. No caps. Bandwidth is always there.

BUT... They use PPPOE (seriously guys?), and the IP changes on *every single re-connect*. Also: no IPv6 support. I know. I don't need it. But I want it.

Enter DNSMadeEasy's DDNS, Hurricane Electric's 6to4 tunnel service, and my Routerboard AH100x4. I wrote a script that runs on the router whenever my IP changes. It updates my DDNS record, updates my 6to4 tunnel IP using HE's API, and updates my local 6to4 interface's IP.

It just works. My public IPv4 may change, but the /48 IPv6 networks on my LAN side stay fully routeable.
