  • network programming - private IP address ranges - Stack Overflow
    What are the private IP address ranges? You will find the answers to this in RFC 1918 Though, I have listed them below for you 10 0 0 0 - 10 255 255 255 (10 8 prefix) 172 16 0 0 - 172 31 255 255 (172 16 12 prefix) 192 168 0 0 - 192 168 255 255 (192 168 16 prefix) It is a common misconception that 169 254 0 0 16 is a private IP address block This is not true It is link local, basically it
  • ip - How many Number of Networks for class B and class C . . . - Stack . . .
    For class B , the number of networks is [(2^14)-2], and the number of hosts is [(2^16)-2] 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
  • 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:
  • 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 )
  • 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
  • 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
  • Getting the IP address of the current machine using Java
    On the face of it, InetAddress getLocalHost() should give you the IP address of this host The problem is that a host could have lots of network interfaces, and an interface could be bound to more than one IP address And to top that, not all IP addresses will be reachable outside of your machine or your LAN
  • 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
  • c - How to find Class, Network Address, Valid host address range . . .
    How to find Class, Network Address, Valid host address range, Broadcast address and default mask of input IP address (Classful) Asked 5 years, 2 months ago Modified 5 years, 2 months ago Viewed 372 times
