  • 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 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 )
  • 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 address ( 255)
  • 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
  • How are the number of blocks for different classes in classful . . .
    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
  • ip - Difference Reserved Class B Networks 192. 168 vs 172. 16 - Stack . . .
    The hosts are in different subnets 192 168 xxx yyy is an ip-block of 256 private class C networks Classed networks assume fixed network masks for particular ip-ranges So, for the networks in block 192 168 xxx yyy, classed-only network software will set the network mask to be equivalent to 255 255 255 0 (or 24)
  • 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
  • How to perfrom subnetting for class B private IP address?
    Suppose you are assigned to design a LAN for an office having 8 departments Each department will have 28 computers located in different rooms Perform subnetting assuming class B private IP address
