With bug 853423 a set of IP ranges were added which are allowed for network connections when the MOZ_DISABLE_NONLOCAL_CONNECTIONS environment variable is set:

https://searchfox.org/mozilla-central/rev/38c88cbf4be87dfa0636d15a5d3599a8ea0d1a72/netwerk/dns/DNS.cpp#188-191

Sadly it misses the range for Shared IPv4 addresses as specified in the RFC 6598. Here an excerpt from chapter 7:

7.  IANA Considerations

   IANA has recorded the allocation of an IPv4 /10 for use as Shared
   Address Space.

   The Shared Address Space address range is 100.64.0.0/10.

The reason why I'm asking for an addition is because currently the co-location I'm working from, and from where I have to run the web-platform-tests hand out local IP addresses of 100.91.x.y, and as such Firefox crashes when I run tests with MOZ_DISABLE_NONLOCAL_CONNECTIONS enabled.
