Study Notes
Network Layer Concepts
- Eight bits of data are referred to as an octet.
- An IP address consists of four octets.
Quality of Service (QoS)
- QoS services allow routers to prioritize certain IP datagrams over others.
- Relevant QoS details are found in the Service Type Field of the IP header.
IP Address Classes
- A Class C IP address falls within the range of 192.37.48.98.
- In a Class A address, the first octet can have a value between 0-127.
Address Resolution
- ARP stands for Address Resolution Protocol, which translates IP addresses to MAC addresses.
Routing Protocols
- CIDR stands for Classless Inter-Domain Routing, which uses subnet masks for network delineation.
- Interior gateway protocols share routing information within a single autonomous system.
- Routers use exterior gateway protocols to communicate data representing the edges of autonomous systems.
IP Address Space
- Defined ranges of non-routable address space include 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16.
- The address that remains the same regardless of network attachment is the MAC Address.
Autonomous System Number (ASN)
- An ASN is 32 bits in length, used for routing and IP address allocation.
Network Management
- The IANA (Internet Assigned Numbers Authority) regulates IP address allocation and ASN allocation.
- RFC stands for Request For Comments, which are documents for discussing internet protocols.
Miscellaneous
- The ARP response informs broadcasting nodes of the MAC address necessary for the destination hardware address.
- Entries in an ARP table expire shortly to accommodate network changes.
- Class E IP addresses are generally reserved for testing purposes.
