Can you have a class C IP address with a subnet mask of 255.255.0.0?
Nov 19, 2014 · Today's Class C with a subnet mask of 255.255.0.0 equals Class B. This is because the subnet is the only remnant of the old Class system, a concept that only exists today in routing tables for quantifying the number of IP addresses in an IP address segment. If one goes back historically to RFC 791 in 1981, subnet masks were not relevant to the ...
Is a class C private IP address range (or even class A or B) both ...
Jun 27, 2018 · The definition of a Class C network address is an address that started with the first three bits as 110. (Class A started with 0, Class B started with 10, Class C started with 110, Class D started with 1110, and Class E started with 1111). Each class A to C had a default mask, but 10.0.0.0 with mask 255.255.255.0 was still a Class A network.
How can you calculate IP address subnet ranges? - Super User
Mar 25, 2015 · Working with a "Class B" or (/16 through /23) works on the same principle as working with /24+. but on a larger scale. With Class C, each CIDR notation is indicative of "Hosts or Nodes" (remember our 64 IP Addresses per Sub-Net). Class B on the other hand is indicative of "Class C Networks". To Compare; Class C: /25 is equal to 128 IP Addresses.
networking - Class c private address of 192.168.1.0 what subnet …
Dec 14, 2015 · As part of a network upgrade, you have been tasked with implementing a new IP addressing structure for the entire campus. You have chosen to use a Class C private IP address of 192.168.1.0. Now you must create separate network IDs for each network while making sure you provide as many host addresses as possible on each network.
Why were the ipv4 private address ranges chosen to be what they …
Class D: Multicast, so its not defined. Class E: Reserved, not defined. The private address ranges are based on the classes and are specified as a specific range over the start addresses of the 3 first classes: Class A: 24-bit Block (/8 prefix, 1 × A) starting with 10.0.0.0 ending at 10.255.255.255 gathering 16777216 different private addresses.
What other IP addresses can/should I use for my home network?
Apr 24, 2015 · So you can use all the IP addresses from 192.168.0.1 to 192.168.255.254 (the first one is reserved and the last one is a broadcast address) really in any way you want and your router allows. The simplest route usually taken in this situation is to use the "sub-subnet" 192.168.0.0/24 or 192.168.1.0/24.
Why subnet mask for IP 10.0.1.4 is 255.255.255.0?
Jul 21, 2016 · 5. The subnet mask specifies which part of the address range will be considered to be part of the network (the subnet) that your computer is on. So if your router has decided to use a subnet mask of 255.255.255.0 and to give you an IP address of 10.0.1.4, that means it is going to be handing out IP addresses in the range from 10.0.1.1 through ...
Why can't I use the first or last address in a subnet?
Aug 9, 2016 · (For completeness...) In addition note that RFC950 discourages the use of the first and last subnets of a class c sub-netted block. This is because the class c network number xxx.xxx.xxx.0/24 is the same as the first subnet in a class c subnet of that block, such as xxx.xxx.xxx.0/27. The last subnet has the same issue regarding the broadcast ...
Why did the IETF specifically choose 192.168/16 to be a private IP ...
Jul 21, 2014 · RFC 1918 which defines the private IP ranges, does not clarify on this point, so there is no definitive answer on why they chose .168 for the 16-bit block, but I posit that this was because the RFC was not released until 1996, after a huge number of registrations had already taken place. because 192 is the first 8-bit block in the class C ...
networking - Class D ip address - Super User
Nov 18, 2014 · Class D IP addresses have the first four bits set to 1110, the rest of the bits are available. So the range for class D addresses is from 224.0.0.0 to 239.255.255.255. And the netmask will be 11110000.00000000.00000000.00000000 in binary and 240.0.0.0 in decimal. The first 4 bits are that..the class ID.
