  Looking at match_prepare_for_sleep() function in systemd-networkd, it
doesn't seem to do anything. So systemd do not touch network when
sleeping.
  But if you use NetworkManager, it has quite comprehensive handling of
the sleep signal. You may want to look at NM configuration to see what
can be done.
  If you're using another network management software, the story can be
similar to NM. Anyway, systemd does not touch network when suspending.
