understanding ip

[upup]

Hi
Type this before but did not seem to go in.

please explain to me;

when log onto network, your ip adress needs to be auto.

When logging unto a device such as a radio with ip, you need to insert a ip on your computer.
said radio is 150.10.10.1 then computer needs to be 150.10.10.2

or when there is more radios linked then you use another and ip [radios=150.10.10.1 , .2 .3 then your computer needs .4 ]

sometimes typing one bit higher dont work [radio .1 you .2 dont work then try .3

How does this work.

Not really sure what the question is. Would like an explanation for having an ip address automatically being assigned on a network vs a static ip for devices? Or you want to know why different ip addresses are not working?

I'm also having trouble deciphering your message but if you are saying your ip always needs to be "1" above the radio (what is this radio?) then that really shouldn't be the case.
if all devices are on a /24 subnet your ip can be any free address from X.1-254

IPv4 addressing is heiraarchical

Class A 1-127
Class B 128-191
Class C 129-223
There are additional Classes beyond this.

Class A (network.node.node.node) has three bytes for the node address of a machine or 16777216 unique combinations.
Class B (network.network.node.node) two bytes for the node address giving 65535 unique nodes.
Class C (network.network.network.node) one byte node address giving 254 unique nodes.
Note that some nodes addresses are reserved

Networks can also be subnetted, that's what the netmask does, this reduces traffic by connecting the networks together with routers or bridges. Way beyond going into here.

And there in lay your issue that you can't see a device at IP address 150.x.x.x when your PC should be set dynamically through DHCP to 10.x.x.x or 192.x.x.x you are on a different network and to see that radio device your IP traffic needs to be routed. You will have an IP address conflict if there is more than one device with the same IP address on the network.

Fixed.

Dyslexic moment, shot

We got different stuff that you need to program or talk to via ip when standing in front of it.

So say you arive at site, look what the device ip are. change your laptop ip to the same ip put say the end is .21 your laptop you make .22
Then you go with IE and talk to it.

My question is.

Why not log in as auto ip.

and also, sometimes choosing one adress higher does not work, but change your laptop ip a bit higher adress.

Hope you understand.
I do this daily and would like to know why I do what I do.

Good question.

Automatically assigned IP addresses require either a DHCP server or APIPA (if the device supports it). You need to configure the mechanism to automatically assign IP addresses. As to why your address does not work, it may be a subnetting issue, or most likely a duplicate IP.

 

[Silver-0-surfer]

maybe it doesn't work because that IP address is already in use on the network?

lol, I'm curious, what do you do you do?

Agree with Conradl,most likely wrong subnet or duplicate IP

I use wikipedia a lot when I come accross something I don't understand
