Study Notes

Binary Representation of Decimal Numbers

The binary equivalent of the decimal number 200 is 11001000.

Class C IP Address Default Mask

The default mask for a Class C IP address is 255.255.255.0.

Network Address Calculation

The network address is calculated by performing a bitwise AND operation on the IP address and its mask.

Subnetting Significance

Subnetting allows for dividing a large network into smaller subnetworks, enhancing network efficiency and security.

IP Address Class

The site address 138.45.0.0 belongs to Class B.

Subnet Requirements

The company's need for subnets is not provided in the given context.

Default Mask Binary Representation

The binary representation of the default mask 255.255.255.0 is 11111111.11111111.11111111.00000000.

Valid Subnetting Technique

Variable Length Subnet Mask (VLSM) allows for splitting a network into smaller networks with different subnet sizes.

IPv6 Address Segment Size

Each segment of an IPv6 address contains 16 bits.

IPv6 Subnet Representation

A subnet number in IPv6 is represented by appending the subnet mask to the IPv6 address, separated by a slash (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334/64).

IPv6 Address Abbreviation

When abbreviating an IPv6 address, leading zeros and consecutive segments of zeros can be omitted, and a double colon (::) can be used to represent one or more consecutive segments of 0s.

IPv6 Address Type

The address 0:0:0:0:0:0:0:1/128 represents a loopback address, also known as a host's own address.

IPv6 Address Zero Segments

The character used to represent one or more consecutive segments of 0s in an IPv6 address is the double colon (::).

Multicast Address in IPv6

A multicast address in IPv6 allows sending data to a group of recipients with a single transmission.

Double Colons in IPv6

Only one double colon (::) is allowed in an IPv6 address.

IPv6 Interface Address

An interface address in IPv6 identifies a specific interface on a network device.

IPv4 and IPv6 Address Size Difference

The primary difference in the address sizes between IPv4 and IPv6 is that IPv6 addresses are 128 bits long while IPv4 addresses are 32 bits long.

IPv6 Address Notation

The correct notation for IPv6 addressing is colon hexadecimal (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

IPv4 Address Space

IPv4 supports 4,294,967,296 unique addresses.

MAC Address OUI Significance

The Organizational Unique Identifier (OUI) in a MAC address identifies the manufacturer of the network interface card (NIC).

Public IP Address Characteristics

A public IP address allows communication with devices on other networks.

IPv4 Address Prefix Notation

The correct prefix notation for the IPv4 address 192.149.252.76 is 192.149.252.76/24.

IPv6 Address Space

IPv6 supports 340 undecillion unique addresses, a staggering number compared to IPv4.

MAC Address Description

A MAC address uniquely identifies a device on a local network.

Anycast Address Function

The primary function of an anycast address in networking is to redirect traffic to the closest device among a group of potential recipients.

TCP and UDP Port Number Range

Valid port numbers in TCP and UDP range from 0 to 65,535.

HTTP Port Number

The port number reserved for the Hypertext Transfer Protocol (HTTP) is 80.

TCP Header Source Port Field

The Source Port field in a TCP header indicates the port number of the sending application on the source computer.

TCP Header Sequence Number Field

The Sequence Number field in a TCP header is 32 bits long.

TCP Acknowledgment Number

The Acknowledgment Number in TCP communications indicates the next byte the receiver expects to receive from the sender.

TCP Checksum Field

The Checksum field in a TCP header is used for error detection during transmission.

TCP Control Bits

The Control Bits in a TCP header provide flags that control the behavior of the TCP connection, such as establishing, ending, or acknowledging data transfer.

TCP Header Length Field

The Header Length field in a TCP header is measured in units of 32-bit words.
