1-10 EXAMINING IPv4 Address Classes Flashcards
What are the address ranges of Class A in IPv4?
1.0.0.0 to 126.0.0.0 (1.0.0.0/8 to 126.0.0.0/8)
Class A supports a vast number of hosts.
What are the address ranges of Class B in IPv4?
128.0.0.0 to 191.255.0.0 (128.0.0.0/16 to 191.255.0.0/16)
Class B is used for medium-sized networks.
What are the address ranges of Class C in IPv4?
192.0.0.0 to 223.255.255.0 (192.0.0.0/24 to 223.255.255.0/24)
Class C is typically used for small businesses.
What are the address ranges of Class D in IPv4?
224.0.0.0 to 239.255.255.255
Class D is used for multicast groups.
What are the address ranges of Class E in IPv4?
240.0.0.0 to 255.255.255.255
Class E is reserved for experimental purposes.
How many networks and hosts can Class A support?
128 networks with approximately 16 million hosts each
Class A is suitable for large organizations.
How many networks and hosts can Class B support?
16,384 networks with 65,534 hosts each
Typically used by universities and regional services.
How many networks and hosts can Class C support?
Over 2 million networks with up to 254 hosts each
Commonly used in local area networks.
How many networks and hosts can Class D support?
Not used for standard host addresses (multicast)
Class D is specifically for multicast groups.
How many networks and hosts can Class E support?
Reserved for experimental; not for general use
Class E is not typically used in practice.
