#isdn adjecent noob question:
The PDH (T1/E1 and stuff) had this problem that each sender had independent clock, which could be slightly faster or slightly slower than the mux, so after some time it may not have sent the next portion of bits when the mux needs to fill its slot in the frame, or […]

I love how with point-to-point links, you don't actually need an IP address (let alone on-link prefix) assigned to the interface.

IPv6 has three kinds of features:
- those that the spec intended, and work
- those that the spec didn't intend, but they still work
- those that the spec intended, but either nobody implemented, or everyone blocks, so they don't work

What if: IPv6 XMAS packet
uses every extension header possible
if any of those have flags, those flags are all enabled
then the last NextHeader says there's another IPv6 inside, and that one is just as festive

how do I use both ULA and proxy-NDP IPv6 addresses on the same link...
OpenWrt's odhcpd can proxy Router Advertisements and override some of the options, but it won't add extra prefixes that the upstream didn't specify :/
Do I try to use SLAAC for proxied addresses and DHCPv6 for ULA?
Or just […]

University elective course idea:
IP Networks based on examples from CTF Tasks
you learn how ICMP, NDP, multicast, etc. works by trying to pwn deliberately misconfigured networks and getting score points in return

TIL in 2014, RFC 7136 oficially called the "universal" and "global" bits in the "interface identifier" part of an IPv6 address to be meaningless and said not to worry about them.
