How names are subdivided (with domain naming) and how networks are
sudivided (with subnetting) have no intrinsic relationship.  You are
free to apply a relationship if that is beneficial but no relationship
is required (or even implied) by the standards.  In fact one of the
subnets here has hosts with names in three (at least) different
domains and each of those domains exist on at least half a dozen
subnets.  The purpose of the hierarchical domain naming system is to
distribute the responsibility for assigning non-conflicting names, the
purpose of subnetting is to ease the design of routing protocols
internal to a single network.
