No, these are services that make the network work.
They are pulled in for network.target, so any service starting after
that will be able to bind to some interface or connect to a remote host.

Sure, I have this mix (for two machines):

rpcbind.service
rpcidmapd.service
rpcstatd.service
wicd.service
ypbind-mt.service
epmd.service
ipsec.service
net at core.service
net-firewall.service
net at he6.service
net-lo.service
net at tnet.service
net at xtit.service

net at .service is just a template to start static network configuration
script, other net-* stuff follows the same purpose, the rest are more or
less what comes with the distro.
I'm fairly sure that common units for other stuff like connman,
wpa_supplicant or dhcpcd will also be in this category.
