Variable length subnet masks (vlsm) allows you to use different masks for each subnet, thereby using address space efficiently vlsm example. Variable length subnet masks allow you a much tighter control over your addressing scheme if you use a class c address with a default subnet mask you end up with one subnet containing 256. Variable-length subnet masks 20145222128/25, and subnet it further into two sub-subnets we do this by taking one bit from the 7 bits left in the host id. Course transcript let's delve a little bit deeper into the topic of subnetting in this case we are going to talk about a concept near and dear to my heart called variable length subnet.
What is variable length subnet mask (vlsm) means subnetting a subnet to simplify further, vlsm is the breaking down of ip addresses into subnets. Vlsm(variable length subnet masks what this means is that if a router running rip has a subnet mask of cidr takes this one step further and allows.

Classless inter-domain routing providing the opportunity to size a network more appropriately for local needs variable-length subnet masks are mentioned in rfc. Vlsm or variable length subnet masking is all subnets have the same number of hosts because they all use the same subnet mask network infrastructure wiki is. The host id portion of an ip address is further divided into a sub-network id part and a host id part the sub-network id is used to uniquely identify the different sub-networks within a.
