Let me be stupid one more time, as these IPs are used by public
WLANs and i did not use 127.0.0.0/8 (-loopback, stupid me)
i started to firewall-block the RFC 5737 TEST-NET-[123] on
ingress, and thus have 192.0.2.0/24, 198.51.100.0/24 and
203.0.113.0/24 guaranteed to be bite-free (and routable via VPN).
