How to attach a static IP to specific PC

[Hikeman]

Hello
I am not sure how much sense does my question make, but here is the situation:
I have a (mostly) wireless network, where only one PC is connect with a wire (LAN) and it has to have a static IP in the network. So it has a stable static IP reassign only to that PC and it works !!! unless some other PC will connect to the network 1st and use that IP THAT IP. When it happens I need to locate the PC in the whole network with THAT IP turn it off that the wired PC can have it's IP, which is very time consuming and annoying (
My question:
Is there a way to prevent that from happening?? How can I stop other PCs using that IP ?

Thank you for reading )) hope to get a solution.
Have a great day

Hi,

Yes, there's a way depending on how you have it set-up. If other PCs on the network are configured to use a dynamic IP address, then you must have a DNS server running, either on your modem or router. Said DNS server can be configured to start from a pool of IP addresses,e.g. 192.168.1.100. Then most routers have the ability to reserve IP addresses to certain MAC addresses too. You honestly have plenty of options to achieve what you want. Care to say what devices you have? Modem/Router/Wireless router?

You will want to do 1 of 2 things.

1.) Setup DHCP reservation on your router for the PC. This will allow only that PC to get the address specified.

2.) Change your DHCP scope on the router so your static address doesn't overlap in your DHCP range.

The Op could also use a static IP that is outside the default DHCP range of IP's without changing the DHCP scope.

For instance, my DHCP server on my router goes from 192.168.0.100 to 192.168.0.199 so the Op can use static IP 192.168.0.200 and be just outside the DHCP range of IP's. No IP conflicts can occur here.

So many ways to fix this although as parman wisely pointed out, I like the DHCP reservation the best because it requires no special static IP settings in the IPv4 properties.

You can also bind two static IP's or even two different subnets to a single NIC by going into the Advanced TCP/IP properties.

Hey guys. Thanks for all your responses.
Let me explain you my problem detailed , that you could possible suggest an easiest way to solve it.
In my network all the other computers has a dynamic IP address, only this one which I am tying to bound to one specific IP address has it static, which is "192.168.1.7" and it HAS to stay unchanged! so what I have to do is to bound this IP to that PC. Default getaway is 192.168.1.1. The router I am using is HUAWEI HG655b. This is the all information that I can think of at the top of my had, if you want me to provide some other inf. pleas let me know, but help me to fix this problem )
Thanks,, have a good day ))

It really depends on whats easiest for your. All solutions above can solve your problem.

If you don't need anything else below 192.168.1.7 Then you can change your DHCP range from 8-254 or how ever many PC's you have.

If you want to setup a dhcp reservation then you have to change the PC from static to dynamic and bind the mac address of the PC to an address.

You will probably have to look into your routers manual to set each of these properly

I don't see a screen for reserving an IP address within the DHCP range:
(sometimes called MAC binding)

But then again - the site above is not showing every screen available... so hard to give click by click instructions.

The manual is of much help either: Downloads - Huawei Device Co., Ltd..

Some routers will not accept traffic from a client with an IP outside of the DHCP range... but the OP can try setting a static IP on the computer with a LAN connection and bump the low end of the DHCP range up above 192.168.1.7 (like others have said).

It looks like you can set it under dhcp under dhcp pool the starting address would be the start of the dynamic addresses and the end would be the last dynamic address in the list

for example, if I had 192.168.1.1 as my gateway, and I wanted to use 10 IP addresses as dynamic but I had a server that needed a static I could put in then starting address for the dhcp pool as 192.168.1.10 and the end address as 192.168.1.19.

I could then set the static address on the server ton anything else in that network range like example 192.168.1.2 and another computer will never try to take that address again because its not in the dhcp pool.

So if I set the DHCP Start IP address from 192.168.1.8, then I can probably fix my problem? I am not pro in this guys, but I do figure out quick, so if you can take a look at the screensoot and tell me what to do??

Thanks

Yes, that is one thing to try.

Change 192.168.1.2 (as shown in your screenshot) to 192.168.1.8

Restart the router.
(If you do not see a way to restart the router via the browser interface,
...turn the router off via a power switch or by pulling the power cord out
...wait a minute or two
...apply power to the router again.)

Restart each computer on the network.

If the computer that has 192.168.1.7 assigned cannot connect to the internet, change the router settings back using one of your other computers.

 

[Parman]

That configuration will work great. If any of your other PC's are getting a dhcp address that is no longer in the range you should run ipconfig /release then ipconfig /renew. So they can be in the current new defined range.

So it is possible for this not to work, too?

 

[Parman]

No it will work. But any pc that has the address of 2-8 will still keep the address until there lease is up so best thing to do is run ipconfig /release and ipconfig /renew for them to get new addresses.

You will need to add the static address for you 1 pc.

I've already answered that question in an earlier post

But I'll repeat it here in more detail. I use a static IP address on a laptop (for reasons that I'll not go into here). When I visit homes in my area to work on computers, I sometimes have to change the DHCP range on their routers to include the static IP address that I'm using or I cannot connect to the internet.

If DHCP is enabled, then all computers must use an IP from the DHCP range.
If DHCP is not enabled, then any statically assigned IP address will get thru.
My guess is that the manufacturer of the routers thinks this is a security feature.
This is not true for all routers - but it is true for most routers in my area.

So - I do not know if it will work for you until you try it.
