The IP header is encapsulated onto - Answers A transport data packet
The IP packet is transported to the next layer where? - Answers Further network information is
encapsulated onto it.
There are two version of IP - Answers Version 4 (IPv4) and Version 6 (IPv6)
What is IPv4? - Answers A router, makes routing decision based on the 32-bit destination
addresses.

All devices connected to the Internet have a? - Answers 32-bit IP address.
Think of IP addresses as a? - Answers Logical address (Possibly Temporary)
While the 48-bit address on every NIC is the? - Answers Physical, or permanent address.
, Computers, networks, and routers use the - Answers 32-bit binary address, but a more readable
form is the dotted decimal notation.
What is an example of a 32-bit binary address? - Answers 10000000 10011100 00001110
00000111
