TCP/IP Basics Chapter 6 Flashcards
What does the command line Address Resolution Protocol (ARP) do?
Protocol used with CMD line command to determine mac address of a an ip address.
CMD command: arp
What is a subnet mask?
The value used in tcp/ip settings to divide the ip address of a host into its component parts. Which are network id and host id
Define Class A Ip Address
First Decimal Value: 1-126
Addresses: 1.0.0.0 - 126.255.255.255
Host per network ID: 16,777,216
Binary Octet Begins with: 0
Define Class B IP Addresses
First Decimal Value: 128-191
Addresses: 128.0.0.0 - 191.255.255.255
Host per network ID: 65,534
Binary Octet Begins with: 10
Define Class C Ip Address
First Decimal Value: 192-223
Addresses: 192.0.0.0 -223.255.255.255
Host per network ID: 254
Binary Octet Begins with: 110
Define Class D IP Addresses
First Decimal Value: 224-239
Addresses: 224.0.0.0 -239.255.255.255
Host per network ID: multicast
Binary Octet Begins with: 1110
Define Class E Ip Addresses
First Decimal Value: 240-255
Addresses: 240.0.0.0 - 255.255.255.255
Host per network ID: experimental
Binary Octet Begins with: 1111
What is classful?
IPv4 address scheme that relied on original class blocks such as Class A, they are obsolete
What is Classless?
IPv4 addressing scheme that does not rely on the original class blocks.
What is CIDR?
Classless Inter-Domain Routing
The basis of allocating and routing classless addresses, not restricting subnet masks to /8 /16 or /24 which classful addressing did
Based on variable-length subnet masking where subnets can be allocated according to the needs of an organization
What is Subnetting?
Taking a block of ip addresses and chopping them into multiple smaller groups!
What is difference between static and dynamic IP addresses
Static: Assigning ip addresses by manually typing them into a computer
Dynamic: Way for computer to receive IP information automatically from a server program DHCP
What is DHCP?
Dynamic Host Configuration Protocol
Sets TCP/IP settings for a client automatically on a network
Which port does DHCP use?
Server UDP 67
Client UDP 68
What is the DHCP 4-way handshake?(DORA)
DISC
OFR
REQ
ACK
DORA
