David,

The loopback interfaces is there as some services and applications
require a network... even on machines without an ethernet card. So
there is a virtual loopback interface there at all times which never
goes down.

You can ping it on IP address 127.0.0.1

IPSEC0-4 are interfaces which deal with possible VPN (Virtual Private
Network) interfaces? Certainly something to do with sending packets
over the network which are encrypted to protect their privacy

Thanks
