TCP/IP Concepts (6.2)

These flashcards cover key vocabulary terms and definitions related to TCP/IP concepts as outlined in the lecture notes.

Transmission Control Protocol/Internet Protocol (TCP/IP)

A suite of communication protocols used to interconnect network devices on the internet.

Network Interface Layer

The 3rd layer of the OSI Model which consists of routers, IP addresses, etc.

Dynamic Host Configuration Protocol (DHCP)

A network management protocol used to automate the process of configuring devices on IP networks.

Internet Protocol version 4 (IPv4)

A communication protocol for data transmission that uses 32-bit addresses arranged in 4 octets divided by dots (i.e., 192.168.1.10)

Subnet Mask

A mask used to determine what portion of an IP address represents the network and which part represents the host.

Network Address Translation (NAT)

A method used by a router to translate between private IP addresses on a local network and public IP addresses used on the internet.

Automatic Private IP Addressing (APIPA)

A feature that allows a device to assign itself an IP address automatically when DHCP is unavailable - 169.254.x.x

IPv6

A communication protocol that uses 128-bit addresses consisting of 8 quartets of hexadecimal numbers separated by colons - 2001:0db8:3c4d:0015:0000:0000:1a2f:1a2b

Address Resolution Protocol (ARP)

A protocol used to translate IP addresses into MAC addresses.

Classes of IPv4 Addresses

Categories of IP addresses used for network addressing, including Class A, Class B, and Class C.

Public Address

An IP address that is routable on the internet and assigned by an Internet Service Provider (ISP).

Private Address

An IP address assigned for use within a local network that cannot be routed on the internet.

Dual Stack

The ability of a device to operate on both IPv4 and IPv6 networks.

Neighbor Discovery (ND)

A protocol in IPv6 used for discovering other network nodes, determining their link-layer addresses, and locating routers.

Static Address

An IP address that is manually assigned to a device, remaining constant over time and not changing unless manually modified.

Reserved Address

An address that is reserved in the DHCP scope by entering a device’s MAC address and mapping it to the reserved address.

IPv6 Prefix

The first four quartets or 64bit of an IPv6 address that identify the network and subnet.

Default Gateway

IP address of a router that is used to reach hosts on remote networks

IPv6 Interface ID

The last 64 bits of an IPv6 address that uniquely identify a device on a network. It is typically derived from the device's MAC address.

IPv6 Double Colon (::)

A shorthand notation used in IPv6 addresses to represent consecutive groups of zeros, allowing for more concise address representation.
