divide it into two subnets?
What does CIDR stand for? Classless Inter-Domain Routing.
What are the five classes of IP addresses? Class A, Class B, Class C, Class D, Class E.
What are the two parts of an IP address? Net ID and Host ID.
In a class-B IP address like 141.14.0.1, what is the net 141.14.0.0.
ID?
What is the purpose of the network mask in IP To determine which part of the IP address is the net ID and which part is the host
addressing? ID.
How many levels do IP addresses have before Two levels: Net ID and Host ID.
subnetting?
How many levels do IP addresses have after subnetting? Three levels: Net ID, Subnet ID, and Host ID.
What is the network address? The first address of each block.
How is the network address calculated? By Boolean 'AND'ing the default mask to any of the addresses in the block.
, TCP/IP Principles | IP Addressing & Routing Concepts | Complete Practice Questions & Verified Answers
What does the default mask reveal in an IP address? It reveals the net ID by setting its bits to 1's and hides the host ID by setting its
bits to 0's.
What is classless addressing? An addressing method with no fixed blocks and no classes, allowing for variable
length blocks.
What is the significance of the prefix in CIDR? It indicates the number of bits used for the network part of the address.
What is the role of routers in IP addressing? Routers calculate network addresses and route packets based on IP addressing.
What is the example calculation for a class-B IP For IP 141.14.0.1, Level One is Net ID 141.14, Level Two is Host ID 141.14.0.1.
address?
What happens to the bits in the network mask during Bits for the net ID are set to 1's, and bits for the host ID are set to 0's.
address calculation?
What is the outcome of using subnetting on an IP It allows for a more efficient use of IP addresses by creating smaller networks.
address?
What is the purpose of the acknowledgment of country in To pay respects to the Traditional Custodians of the land.
the lecture notes?
What defines the NET-ID in variable length address The NET-ID is defined solely by the Prefix.
blocks?
What must the number of addresses in a variable length The number of addresses must be a power of 2.
address block be?
What is the requirement for the first address in a variable The first address must be evenly divisible by the total number of addresses in the
length address block? block.
What is the format of a Classless Address? The format is x.y.z.t/n, where n is the prefix.
What does the prefix /22 represent in the address The prefix /22 defines the net-ID and corresponds to the subnet mask
184.13.152.0/22? 255.255.252.0.
What are the components of classless terms? Prefix, Suffix, and n.
How is the host-ID determined in a Classless Address? The host-ID is the remaining bits after the prefix, calculated as (32 - prefix
length).
