Some troubleshooting info for those who care.  HTH.

207.75.116.0/22 might be unreachable, in the sense that packets are
being lost/dropped.  Things like 207.75.116.50 (public MX/SMTP server
for radb.net) also do not respond (on TCP port 25); note that's in a
different /24 than 207.75.117.70.  The /22 is part of advertised route
207.72.0.0/14.

Packets make it all the way into part of merit.edu's network on AS237,
but die after hitting a edge/border router or firewall.

Tried poking merit.edu's publicly authoritative DNS servers
(198.108.1.43, 198.108.130.10, and 198.109.36.10); the latter two
respond (CNAME to Cloudflare), while 198.108.1.43 times out (SERVFAIL).
And yes, the behaviour is the same if explicitly querying for CNAME
rather than A.  Might be a different matter though.

Also noticed that whois.radb.net (198.108.0.18) isn't responding
either (tried both RWHOIS and WHOIS ports).
