Describe the 4 Common Principles of Internet Addressing that most Networks follow?
- Give the Default Gateway the first IP Address in the Network ID.
- Try to use the remaining IP Addresses in sequential order.
- Try to separate Servers from Clients
- Document whatever you choose to do so the person who comes after you understands.
What is the one major problem with Static Addressing?
Making any changes to the Network may be difficult.
What are two goals of Subnetting?
- Efficiency
2. Making multiple Network IDs from a single Network ID.
Define a DHCP Lease and describe how it is used?
DHCP Lease is set for a fixed/limited amount of time, often one to eight days.
Near the end of the Lease time, the DHCP client sends another DHCP Request.
Define the Default Gateway on a TCP/IP Network and briefly describe how it is set up?
Default Gateway is the Router, which is basically the “Gateway” from the LAN to reach the Internet.
Your LAN gets connected to the Router, when the Client on the Network needs to reach the Internet, the Segment is “Routed” through the Router and the Router - using its Routing Tables sends it off, the Segment will go from Router to Router known as Hops until it reaches its Destination.
For Logical Addressing to work, no two computers on the same Network may have the same _________?
IP Address
To make IP Addresses easier for humans to use, the 32-bit binary value is broken down into ____________ groups of eight, separated by periods, or dots?
four
