Geoff on IPv4 Exhaustion

[Frank Bulk]

An RA spoofer wouldn't cross L3 boundaries, which is what a DHCPv6
relay/LDRA can perform today.

After so many years of shouting I thought everyone was clear,
the people who want DHCP want it to control everything they don't
want RA at all so having to run RA to give clients permission
to use DHCP is thus broken, as you say if they were willing to run
RA then they'd not be needing routing info in DHCP

Of course DHCP servers could come with a spoof RA generator to
give themselves permission to be the DHCP and control everything
including default router from the DHCP box config. There's probably
some reason I've not looked for why this won't work as I'd have
expected them to have done this already as temporary fix
