IP routing
Routing is the process of sending a packet from the source address to the destination address. Because all IP packets have a source and destination IP address, it is possible to deliver them to the proper location.
IP Security Monitor
Tool that can be used to validate that communications between hosts are indeed secure. It provides information such as which IPSec policy is active and whether a secure communication channel is being established between computers.
IPSec
A set of protocols used to support the secure exchange of data at the IP layer using encryption. In Transport mode, only the data portion or payload is encrypted. In Tunnel mode, both the header and the payload are encrypted.
iterative query
With an iterative query, the DNS server uses zone information and its cache to return the best possible answer to the client. If the DNS server does not have the requested information, it can refer the client to another DNS server.
