Why does the host need to know its subnet mask?
The subnet mask identifies which IP addresses are local and which IP addresses are remote. Anything that has an IP address, whether computer or router, needs a subnet mask. Lets use an an example, an IP address with 192,168.1.
What happens with wrong subnet mask?
Incorrect Subnet Mask: If a network uses a subnet mask other than the default mask for its address class, and a client is still configured with the default subnet mask for the address class, communication will fail to some nearby networks but not to distant ones.
What is difference between subnetting and VLAN?
At a high level, subnets and VLANs are analogous in that they both deal with segmenting or partitioning a portion of the network. However, VLANs are data link layer (OSI layer 2) constructs, while subnets are network layer (OSI layer 3) IP constructs, and they address (no pun intended) different issues on a network.
Why do we need a subnet mask in networking?
Why do we need a subnet mask? – A subnet mask allows identification of host part and network part of an IP address. – Subnet mask can be used to find if an IP address is present on a subnet or not. – Subnet mask is utilized for isolating the network id and host ids.
When was subnet masking introduced in classless routing?
Classless Inter-Domain Routing was introduced in 1993 to replace the classful network design. Instead of allocating network addresses using address classes based on 8 bit groups it uses variable length subnet masking. It also introduced a new method of denoting network masks.
What is the easiest mask to use to satisfy the criteria?
– You have been allocated a class B network address of 135.1.0.0 and and need to create 4 subnets each with around 200 hosts what is the easiest mask to use to satisfy the criteria? Easiest is to sub net on a byte boundary which would mean a subnet mask of 255.255.255.0 This would allocate 8 bits for the subnet and 8 bits for the host.
Is the host part the same as the network part?
Think about the Network part as a multi dueling Building Address number, and the Host part as your apartment number inside this building. For example, building address “Building XYZ” is the network IP address part, and “Apartment number 2” is the host address part.
