- Whats the difference between IP address 0. 0. 0. 0 and 127. 0. 0. 1?
Just that, "this host on this network" as Lee B's answer states this translates to all available IP addresses on your host Hosting a service on 0 0 0 0 will automatically host that service on every addressable interface 127 0 0 1: From RFC5735: 127 0 0 0 8 - This block is assigned for use as the Internet host loopback address
- What is the difference between 0. 0. 0. 0 0 and 0. 0. 0. 0 1? - Server Fault
Therefore, by splitting the 0 0 0 0 0 into smaller chunks one can constrain the interface to take precedence over any other interface that has default route 0 0 0 0 0, without playing with metric values This is a common technique with VPNs that would not want data to bypass the tunnel
- What is the meaning of 0. 0. 0. 0 as a gateway? - Unix Linux Stack Exchange
When 0 0 0 0 is specified as the Gateway, it means: read the line with 0 0 0 0 as the destination and route the packet through this interface But when you have a second network interface or more, you can have the IP of one of those network interfaces specified as the Gateway instead of 0 0 0 0, and packets will be routed through them
- Whats the difference between 127. 0. 0. 1 and 0. 0. 0. 0?
You can use the wildcard 0 0 0 0 in contexts where an address can be optionally provided, to mean I don't care For example, when you actively open a TCP connection to some TCP server (a TCP server is created by a passive TCP open), you need to specify the address of the TCP server (IP and port number), and you can optionally choose a local
- How to communicate with a device that has an assigned “0. 0. 0. 0” IP address?
It shows 0 0 0 0 as a way to signal that it failed to assign an IP address 2 It has a broken IP stack which somehow managed to assign itself 0 0 0 0 I don't know enough about VxWorks to say which of the two is most likely If it really has assigned address 0 0 0 0 you'd need a hacked up IP stack to communicate with it But that will not do
- Why cant IP addresses start with 0 or 255? - Super User
0 0 0 0 8 and 255 0 0 0 8 are both reserved by IANA in 1981 The former block is for self-identification (based on RFC 6890) and the latter is reserved for "Future use"; formally Class E Addresses starting with 240 or a higher number have not been allocated and should not be used, apart from 255 255 255 255, which is used for "limited
- What does 0. 0. 0. 0 gateway mean in routing table? - Super User
Note that a gateway is an IP address to which you send packets for a specific network The default gateway is an IP address to which you send packets that have no other matches in the routing table
- What is a subnet mask, and the difference between a subnet mask of 255 . . .
Consider the class A network 10 0 0 0 to 10 255 255 255 (this is the designated "private" class A block i e packets destined for these addresses will not be routed) In binary the addresses are: 00001010 00000000 00000000 00000000 through to 00001010 11111111 11111111 11111111
