Study Notes
IPv4 Addresses
- Valid IPv4 addresses include 2.2.2.2 and 172.16.1.26.
- Class A, Class B, and Class C are classifications of IP addresses, with examples like 124.77.8.5 (Class A), 131.11.0.9 (Class B), and 196.5.89.44 (Class C).
Subnet Masks and CIDR Notation
- Default subnet mask of 255.255.0.0 is associated with addresses like 129.0.0.1 and 168.16.5.1.
- The default subnet mask for the IP address 203.111.3.3 is 255.255.255.0.
- CIDR notation for a host with 129.11.99.78 and a default mask is 129.11.99.78/16.
Subnetting Concepts
- Supernetting refers to using a subnet address like 198.162.1.0/23.
- Subnets facilitate the division of an IP network into multiple network addresses.
IP Addressing in Networking
- Classless addressing is reflected in the IP address 192.168.255.188 with a mask of 255.255.0.0.
- IANA is responsible for the allocation of public IP addresses.
Configuring Network Devices
- When subnetting with a mask of 255.255.192.0 on the 172.17.0.0 network, network IDs can be 172.17.0.0 and 172.17.128.0.
- The default gateway for a workstation (Wrk1) to communicate with the internet is the IP address assigned to Fa0/0 on Router1.
- For workstation configuration, use the following:
- IP Address: 192.168.12.46
- Subnet Mask: 255.255.255.240
- Default Gateway: 192.168.12.34
- DNS Server: 198.162.1.22.
Troubleshooting Network Issues
- Implementing an IP Helper address on the router can resolve issues where hosts on new network segments cannot communicate with a DHCP server.
