IP (Internet Protocol) is the main network layer protocol utilized on the Internet. IP is responsible for addressing and fragmentation. IP works with another network layer protocol, ICMP. Transport layer protocols which utilize IP include TCP and UDP.
IP Addresses
IP addresses are four octets (32 bits) long and are usually seperated by periods. Some example IP addresses are:
127.0.0.1
10.0.0.1
38.250.25.1
IP addresses are using in routing packets through the Internet.

A computer network can be segmented physically and logically. A collision domain is one of the logical network segments in which the data packets can collide with each other. One of the most common protocols used when referring to a collision domain is the Ethernet protocol. Collision domains are often referred to as 'Ethernet segments.'
The term 'collision domain' is also used when describing the circumstances in which a single network device sends packets throughout a network segment and fo

A DHCP reservation is a permanent IP address assignment. It is a specific IP address within a DHCP scope that is permanently reserved for leased use to a specific DHCP client.
Users can configure a DHCP reservation in their DHCP server when they need to reserve a permanent IP address assignment. Reservations are used for DHCP enabled devices like print and file servers or other application servers that always have the fixed IP address on the network.
A reservation consists of the following

A static route is one that a network administrator creates manually.
The opposite of a static route is a dynamic route. Dynamic routes are created by routing protocols.
Static routes have advantages and disadvantages when compared to dynamic routes.
Advantages of Static Routes:
Easy to configure
No routing protocol overhead
Disadvantages of Static Routes:
Network changes require manual reconfiguration
Network outages cannot be automatically routed around

Routing is the process of moving packets through an internetwork, such as the Internet.
Routing actually consists of two separate, but related, tasks:
Defining paths for the transmission of packets through an internetwork.
Forwarding packets based upon the defined paths.
Routing takes place in IP networks, based on IP routing tables and its entries. The information in the IP routing tables is used by IP hosts to transfer data over the internetwork. Routers are devices operating a
