Hm, I guess you mean VPN over IP

VPN is a pretty generic description. Its primary 'goal' is to
describe a technology of choice which is capable to create
a private topology over a public one.

GRE, IPSec, L2TP, PPTP, IP-IP Tunnel, IP tunnelled in ATM/FR, ..
many possible things :)

VPN-IP would not describe which encryption (if needed, that's not
typical per se) is used, so

VPN, using IP as transport and IPSec for tunneling/encryption.
 (you can use IPSec w/o encryption too)

Note: 'VPN' is too complex to put it in short words :-)
