+For each supported `PF_*` protocol family (domain), there is a file `/servers/socket/N`
+where `N` is the numberic value for the `PF_*` symbol.  Right now
+[[`PF_LOCAL`|translator/pflocal]] (a.k.a. `PF_UNIX` or `AF_UNIX`) `N=1`,
+[[`PF_INET`|translator/pfinet]] (a.k.a `AF_INET`) `N=2` and
+[[`PF_INET6`|translator/pfinet/ipv6]] (a.k.a `AF_INET6`) `N=26` are supported.

+Depending on the socket domain used the libc function `_hurd_socket_server`
+is called from the calling function socket/socketpair, resolving the socket
+server to use `/hurd/pflocal` or `/hurd/pfinet`. In case of problems to find
+out which server is called rpctrace can be of use: The server is found with the
+`dir_lookup` RPC.
 
 User programs open those files, and use the `socket_create` [[RPC]] to make a
 new socket.  With that socket, they can use the other `socket_*` RPCs and also
