- ip address - How many number of hosts do IP classes A, B, and C have . . .
There are also Special Use Addresses within those classes, like loopback, private network, link-local addresses and so on The difference in number of addresses available between Class A, B and C networks is due to leading bit prefix length (1 bit for Class A, 2 bits for Class B, 3 bits for Class C) To answer your question:
- Why do class D and E IP-addresses have no subnet mask?
We have not had network classes in this century Multicast (former Class D) uses individual addresses for groups of hosts, and it has no network concept that needs network masks The Reserved addresses (former Class E) cannot be used, so there is no network concept that needs network masks
- linux print directly to network printer that IS NOT installed
I need to build a simple web based printer server that will print a file to any given printers IP address Using lp or lpr how can I print a file directly to a network printer by IP address? NOTE:
- Difference Reserved Class B Networks 192. 168 vs 172. 16
A 'network' or 'subnet' is a set of ip-numbers that can connect to each other without the use of a router A class C network has a maximum of 256 such ip-addresses To get from one subnet to another subnet, a router is required You can not call the 192 168 xxx yyy block a single class B subnet, because the hosts at 192 168 1 xxx cannot directly connect to hosts in 192 168 2 xxx The hosts are
- How do we determine the class of the IP address?
How could 128 138 243 100 26 be class B if we flow rule 1 Since rule 1 says class B should be N N H H but in the above example clearly the N part of the IP address is beyond N N N (here it even encroaches two bit of the H )
- ip - What is exactly a default (classful) network mask? - Stack Overflow
0 I know that each IP class has a default network mask (class A: 255 0 0 0, class B: 255 255 0 0 and class C: 255 255 255 0) I have been reading the subnetting net tutorial and they use the default (classful) network mask for subnetting (Question Type 2 Written Example), but on the other hand I read all the time that IP classes are obsolete
- ip - How many Number of Networks for class B and class C . . . - Stack . . .
For class C , the number of networks is [(2^21)-2], and the number of hosts is [(2^8)-2] The "-2" is because the first address for each range is reserved for identify localhost or local network address ( 0), and the last one is the broadcast address ( 255)
- network programming - How are the number of blocks for different . . .
netid = number of blocks hostid = block size IP address has total of 4 bytes and is divided into 5 classes depending on the initial bit (s) In class A, one byte define the netid and 3 bytes defines the hostid In class B, two bytes define the netid and 2 bytes defines the hostid In class C, three bytes define the netid and 1 byte defines the hostid Hence; for A number of blocks = 2^7 as 1
