What is the network portion of IP 172.16 0.0 16?
Assume we have been assigned network address 172.16. 0.0/16. The subnet mask associated with that address is 255.255….2.3 Subnets.
| Network Number | First Address | Last Address |
|---|---|---|
| 172.16.0.0 | 172.16.0.1 | 172.16.15.254 |
| 172.16.16.0 | 172.16.16.1 | 172.16.31.254 |
| 172.16.32.0 | 172.16.32.1 | 172.16.47.254 |
| 172.16.48.0 | 172.16.48.1 | 172.16.63.254 |

What is Vlsm Cisco?
A Variable Length Subnet Mask (VLSM) is a means of allocating IP addressing resources to subnets according to their individual need rather than some. general network-wide rule. Of the IP routing protocols supported by Cisco,OSPF, Dual IS-IS, BGP-4, and EIGRP support “classless” or VLSM routes.
What does a subnet mask of 0.0 0.0 mean?
the default route
Routing. In the context of routing tables, a network destination of 0.0. 0.0 is used with a network mask of 0 to depict the default route as a destination subnet. This destination is expressed as 0.0.
How many host does the 22 has?
So if I’m not mistaken, /22 is 1024 (2^10) hosts.
What is the difference between subnet and host?
A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs.
What’s the difference between VLSM and subnetting?
FLSM subnetting vs. FLSM creates subnets of the same size and an equal number of host identifiers, while VLSM creates subnets with varying sizes with a variable number of hosts.
What are the disadvantages of VLSM?
Some of the disadvantages of VLSM are as follows: It is easy to make mistakes in address assignment, so double-check your calculations before deploying them. It is more confusing and difficult to monitor your network with all the new subnets.
