The license key field max-domains is a bit of a misnomer. It should have been called max-routes, but it is easier for people to think in terms of domains and in the majority of cases routing is by-domain only.

However, our logic counts all route: records, regardless of type, towards the license's max-domains, since the same amount of work is necessary to route by-domain as by-address or by-account.
