May 26, 2023 · The slash and the number following it is just a shorthand way to write a subnet mask. It's called CIDR (Classless Inter-Domain Routing) notation. It's also commonly referred to as the prefix length. The number after the slash represents the …
IPv6 addressing (slash notation) - Network Engineering Stack …
Apr 29, 2016 · The slash notation is another way of writing the subnet mask. It works the same for IPv4 and IPv6. The number /3 indicates the number of consecutive 1's in the mask. Since the mask is the same size as the address, that means that for IPv6, the subnet mask is three 1's followed by 125 0's (3+125=128 bits).
ipv4 - How is the IP prefix passed to the router? - Network …
Feb 20, 2014 · Since the prefix length cannot be inferred from the IP address alone, routing protocols must carry the prefixes to routers. Sometimes prefixes are simply de- scribed by their length, as in a ‘‘/16’’ which is pronounced ‘‘slash 16.’’ The length of the prefix corresponds to a binary mask of 1s in the network portion.
routing table What does this mean (brackets in routing table)?
Nov 10, 2022 · Looking at the default route (0.0.0.0/0) as example, you have two sets of brackets. The first brackets shows the routing admin distance: [10/0] on the first and second, and [20/0] on the third.
calculate # of subnets and - Network Engineering Stack Exchange
The question is asking you to take the large network (with the slash notation) and divide it up into smaller subnets, each one using the given subnet mask. So if you have a network 128/8 (or more correctly, 128.0.0.0/8), and you want to subdivide it into smaller subnets using the mask 255.255.255.128, how many subnets can you make?
How to interpret subnet mask - Network Engineering Stack …
Nov 12, 2019 · with the slash notation it is written as /22 or /24; in decimal, it will be 255.255.252.0 or 255.255.255.0; As you can see the 22or 24 noted after the slash is simply the count of contiguous 1. The decimal notation divides the 32 bits in four octets and convert them from binary to decimal and write them separated by points, the same way an IP ...

Mar 19, 2019 · That would not be called an ethernet cable, it is UTP cable, and it can be used for ethernet, token ring, POTS, serial, etc. Ethernet runs on a variety of media, including coax, twisted-pair, optical fiber, etc.
What are the subnet masks for the following slash address blocks?
Apr 4, 2016 · The number after the slash tells you the number of consecutive 1s in the mask. So in the first example, there are eight consecutive ones: 11111111 00000000 00000000 00000000 When you write that in dotted decimal notation, you get . 255.0.0.0 The next example: 11111111 11111110 00000000 00000000 or 255.254.0.0 I'll leave the last one to you ;)
What is the practical use of a /31 CIDR or 255.255.255.254?
Jul 23, 2018 · @rnxrx, I understand that, but the comment asked about using it for equipment that does support it. Also, there is no good excuse for not supporting IPv6 /127 point-to-point links (hello, Verizon, AT&T, Century Link, etc.). At least Microsoft got it right for IPv6, even if they will never support IPv4 /31 networks. –
What is the proper term for ipaddress/hostname:port
Jun 17, 2014 · What is the proper term for (example) hostname.tld:433 (hostname:portnumber)? It is not just hostname, and it is not really a URL either :) same goes for 10.0.0.1:3306 etc.
