  1. What does /16,/24 mean with regards to ip addresses?

    2019年7月26日 · /16, /24 is called CIDR notation, it's a different way to express the subnet mask. A subnet mask can be used for any IP, public, private, etc.; the /X has nothing do really whether the IP is public or private. Electronic equipment processes IP addresses as a string of 32 bits that can either be 1 or 0.

  2. What does this mean /16 after an IP address - linux

    2020年1月12日 · However, an IP number that starts with 255, similar to the one you wrote 255.255.255.1/16 is usually used only for netmask and means that the first 16 bits are fixed and the rest may change. A mask of 255.255.0.0 and an a.b.c.d/16 have the exact same masking bits (or …

  3. ipv4 - The slash after an IP Address - CIDR Notation - Network ...

    2023年5月26日 · 2) The number of bits (from left to right) that represent the subnet address is specified as 16 ('/16'). 16 bits, or 11000000.10101000 (192.168) is the network address and 0.0, or 00000000.00000000, is the host address - in this case a broadcast address.

  4. How to find the first and last address in the FIRST AND LAST SUBNET

    2020年10月5日 · 1024 = 2^10. That means on top of the /16, you use 10 bits to identify the subnet. The consequence is that those subnets are /(16+10) = /26 networks. This leave you with 32-26 = 6 bits for the hosts. So you have 2^6 = 64 addresses per subnet, including the network and broadcast addresses.

  5. What does it mean to have a subnet mask /32? - Super User

    2019年8月20日 · A /16 IPv4 network has a subnet mask of 1111.1111.0000.0000, meaning the first 2 octets are the network ID and the last octet is used for assigning host IDs (65536 available IDs, though usually some are reserved). In the case of /32, this doesn't apply as the address is both a network ID and host ID.

  6. ip - Class B subnetting and subnet mask - Super User

    2017年1月23日 · we will take 4 bits to have 16 networks that can fit the request , so my new subnet mask is : 255.255.240 .0 now , the first three networks are (the magic number is 16 ): First network : 172.16.0.0

  7. Usage of 192.168.xxx, 172.xxx and 10.xxx in private networks

    2020年1月20日 · The deal is that everything else, with the exception of a few other restricted subnets (such as multicast, localhost, APIPA, etc.) are routable on the internet, so if you decide to use something other than 192.168.0.0/16, 172.16.0.0/12, or 10.0.0.0/8 privately (in an IPv4 network), such as 100.200.0.0/16, keep in mind that you will not be able ...

  8. Communicating with devices on a different subnet - Super User

    2015年1月6日 · For your computer to talk to any computer, your system must have an entry in its local routing table (or Forwarding Information Base) for that subnet. A subnet is a network address plus a subnet mask. (Note that the subnet mask can be in dotted form (255.255.255.0) or CIDR form (/24) - they express the same thing though certain things want only ...

  9. How do you calculate the prefix, network, subnet, and host …

    And for creating 4 subnets, we use the 22nd and 23rd bit as 00, 01, 10, 11 leaving the last 9 bits as is. So the first subnet would be 21 1s and rest all 0s. @nd subnet would be 21 1s, followed by a 0 (22nd bit) and then 1(23rd bit) and then rest all 0s. 10000000 00101010 00000001 00000000 which is 128.42.2.0. Similarly 00000010 is 4. 00000011 is 6

  10. Understanding the RFC1918 IP address range - Super User

    2015年11月30日 · 172.16.0.0/12; 192.168.0.0/16; You can subnet within each one of those ranges. For instance, 192.168.1.0/24 is a subnet within the 192.168.0.0/16 network. So is what you say you use: 192.168.2.0/24. It all boils down to …
