- What is the practical use of a 31 CIDR or 255. 255. 255. 254?
With a 31 subnet, we are left with zero usable hosts The 31 subnet only has two hosts - one for network and another for broadcast I am wondering why would someone ever use this subnet
- subnet - Whats the different between a mask in route table and . . .
A subnet mask is used to divide the IP address into network address and host address In this example the subnet mask 255 255 255 0 equals to 11111111 11111111 11111111 00000000 which is the equivalent of it in bits, stating that it has 256 hosts in which 254 are available
- How do you calculate the prefix, network, subnet, and host numbers?
28 Part 1 of 2 IPv4 Math With an IPv4 address and the network mask, the network mask length, or host mask, you can calculate the Network Address, Broadcast Address, Total Addresses, Usable Addresses, First Usable Address, and Last Usable Address It cannot be stressed enough that you must do IPv4 math in binary
- ipv4 - What is the correct mask to use with 224. 0. 0. 0? - Network . . .
What is the best mask to use to allow computers to use the multicast IP address 224 0 0 0? I've only seen IP addresses using the lower 8 bits, in my case I just see 22 and 251

- The slash after an IP Address - CIDR Notation
The slash following the IP address is the abbreviation for the subnet mask The binary version of a subnet mask is going to be comprised of ones and zeros just as the binary verison of an IP address would be, however, the ones in a subnet mask are all consecutive The amount of ones in the subnet mask is equal to the number of the abbreviation For example, the 16 subnet mask you asked about
- Communication between different subnet MASKS with IP address that works . . .
ARP requests do not include any data about subnet masks, so there is no way for Host B (or A) to know that the other host has a different subnet mask at this point Host A now has Host B's MAC address, and will send a layer 2 frame with her MAC address as the source and his MAC as the destination, which the switch will happily pass along
- What is the point of a subnet mask on a local network?
I have a question regarding subnet masks and my understanding (or misunderstanding of them) So when a subnet mask is used, a bitwise AND is performed using the subnet mask and the IP address(es)
