The Exit flag only request one IPv4 /8 :

But if the network health team is testing a different IPv4 /8, then your
relay might appear down.

(If the DNS for the site they are testing has both IPv4 and IPv6, then
the outcome will depend on their tor version and config. 0.4.3 and
later will prefer IPv6 by default.)
