What is the difference between a MAC address and an IP address? Which address can you assign to a computer?
MAC address is physical (cannot change). IP address is logical address
How does the IP address indicate both the network and the node address? What is used to identify each part of the address?
Subnet mask. Octet with numbers between 1-255
What is the address class of IP address 133.66.155.189?
Class B
What is the default subnet mask for the IP address 166.88.1.45? What is the network address? What is the host address?
255.255.0.0, The network address is 255.255, the host address is 1.45
What happens to the MAC address when you move a computer to another network?
Physical address remains the same
MAC
Media Access Control, physical address
What has a MAC address?
Every computer(even network printers)
IEEE
Institute of Electrical and Electronic Engineers
MAC numbers
48-bit, 12 hex, numbers range from 0-9, A-F
Hexidecimal
Base 16 counting system, the first 6 numbers are unique to the manufacturer. The last six characters are unique to that particular network board.
IPV4
Octet(binary), 3#.3#.1#.2#.Maximum number is 255.
Subnet mask
Helps you figure out how much of an IP address is the network address.
IP Address that ends in 0
Network address
255.0.0.0, look at the first octet value. If between 1-126 Class A IP address. First octet is network and the rest is host
Class A IP Address
255.255.0.0. 128-191(first octet).
Class B IP Address
255.255.255.0, if between 192-223 in first octet. Host # can only be 0-254
Class C IP Address
What is 255 in a host used for?
Broadcasts
Multicast address, first octet value is between 224-239.
Class D Address
240-255
Class E IP Address
What is an IP address class?
Defines the default network address portion of the IP address
255.0.0.0
Class A default subnet mask
255.255.0.0
Class B default subnet mask
255.255.255.0
Class C default subnet mask
