Here this is NFS4 over TCP:

filer.lip.ens-lyon.fr:/export/home/vlefevre on /home/vlefevre type nfs4 (rw,nosuid,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=140.77.14.11,local_lock=none,addr=140.77.14.5)

Is there any other information I could get?
