Study Notes
- This YouTube video is the fourth lesson under Network design and implementation on the Ed XL it Guru channel.
- IP addressing is unique to each device connected to a network, allowing communication between devices.
- IP addresses consist of four segments, each with values ranging from 0 to 224.
- IP addresses serve to identify devices uniquely within a network and provide location information.
- IP addresses work similarly to house addresses, with source and destination addresses stamped on data packets for routing.
- Private IP addresses are used for devices within private networks, such as homes and offices.
- Public IP addresses are used for devices accessing the internet.
- Static IP addresses are permanently assigned to devices, while dynamic IP addresses are assigned when connecting to a network.
- Shared IP addresses are assigned to multiple virtual devices, while dedicated IP addresses are assigned to specific sites or devices.
- Logical IP addresses are assigned by software, while physical IP addresses are built into hardware.
- IPv4 and IPv6 are the main IP address versions, with IPv4 being the original and widely adopted version, and IPv6 having a larger address pool and more security features.
- Mac addresses are unique identifiers assigned to network interfaces for use on the local network, responsible for local identification.
- Mac addresses are 48 bits long and work in the second layer (link layer) of the OSI model, while IP addresses are 32 bits long and work in the third layer (network layer).
- Mac addresses are fixed and assigned by manufacturers, while IP addresses can change depending on the network environment.
- Mobile devices can connect to wireless networks using dynamic IP addresses for temporary assignments.
- Mac addresses are used to identify devices for making connections and to reconnect in case of interruptions.
