What does /16,/24 mean with regards to ip addresses?
网页2019年7月26日 · 39. /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.
What does this mean /16 after an IP address - Unix & Linux Stack …
网页2020年1月12日 · An /16 is usually used to indicate the number of bits that are fixed (would not change) in a range of addresses of a network. That is a simpler syntax to express the CIDR. Having an IP number as 1.2.255.1/16 means that any address from 1.2.0.0 up to 1.2.255.255 is part of that address range or network. …
What does it mean to have a subnet mask /32? - Super User
网页2019年8月20日 · 6. easiest thing is web search and read articles related to subnet mask and subnet mask binary shorthand and CIDR. and also check out subnet calculators. the /32 is the CIDR (shorthand) and refers to how many 1's are in the subnet mask. For /32 that is 255.255.255.255 or 11111111.11111111.11111111.1111111.
Why my subnet mask is not matching with my IP address?
网页2014年2月10日 · And when u changed the IP to a Class B address, the sub-net mask that does not change by default, remained as 255.255.255.0. In windows machines, sub-net mask is not auto-assigned when IPs are changed/edited. If you use a 172.16.x.y IP address and a 255.255.255.z mask, the Host range will depend on value 'z'.
How do I get a /23 subnet mask from 172.16.0.0 /21 network …
网页2014年3月2日 · I know I need a /23 subnet mask, but I don’'t know how to do that from the above information. I need: 255.255.254.0 11111111.11111111.11111110.00000000 In the previous paragraph, I get this binary 2 is the “magic number” and my subnet IP address will increase by two.
How to find how many hosts are on subnet mask: 255.255.255.252?
网页255.255.255.252 is a /30 network mask (or simply netmask), that is, the first 30 bits are used for the network prefix and the last 2 are use to identify the host. Such a netmask has 64 subnets and 2 hosts in each subnet for a total of 128 hosts: network address x.x.x.0. first host x.x.x.1. last host x.x.x.2.
What is the diference between IP subnet mask 255.255.254 .0 ... or …
网页2015年7月2日 · That is the ip of the subnet itself. 192.168.1.1-192.168.1.254 are all valid IPs That can be assigned to client devices. Finally, 192.168.1.255 would be the broadcast address. This contrasts with the subnet mask 255.255.254.0 in that it offers 510 valid IP addresses. Still one for the subnet itself and one for the broadcast. Another example for ...

网页2015年1月6日 · You also get a free routing table entry for your loopback address. 127.0.0.1/8. If you add another ethernet interface, let's say a USB one, and manually configure it with an IP, say 192.168.10.1, the same thing happens above with free routes. Assumne you assigned the USB ethernet adapter 192.168.10.1 with subnet mask /24 …
Why isn't 255.255.249.0 a valid subnet mask? - Super User
网页2021年3月31日 · The only outstanding constraint is that the mask must be left contiguous. For example, convert a valid netmask 255.255.248.0 to binary: All the "1"-bits are at the beginning, which means the mask always matches a prefix – the first 21 bits define the network. (This means the whole 255.255.248.0 netmask can be written as "/21" for short.)
Implications of incorrectly configured subnet mask / gateway
网页2018年4月16日 · The SVI had the following parameters; Network Addr: 192.168.65.96 Subnet Mask: 255.255.255.248 SVI Addr: 192.168.65.102. There were two devices on this subnet and, when the the change was made both devices were still able to communicate to the remote network even though the default gateway and subnet mask were 192.168.65.1 / 255.255.255.0 ...
