Windows 10: Stop local IP address from changing a few hours after boot time

Hi folks

I've only noticed this recently after ISP upgraded its network. I have a Linux NAS sysem server which serves to a few Windows clients .

The server gets at boot time an assigned an IP address via DHCP -- that's fine - I rarely re-boot the server - but since the ISP upgrade the local IP address changes after a few hours for example from 192.168.1.20 to 192.168.1.27 -- this means that all the Windows clients go Bonkers as they can't see the server any more.

I get round this by stopping and restarting the samba services (smb(d) and nmb(d) and then the Windows clients can immediately see the server again without them having to do anything like re-booting their machines but it's a pain to have to do this. Also if I'm away you can imagine if the Windows clients can't get their video streams, backups or files etc.

However while your external IP address (the one people see on the Public Internet) can change and that's fine why on earth should the local addresses be affected. I really want to get away from using fixed local IP addresses.

There doesn't seem to be any settings on the router to preserve DHCP assigned addresses either.

here the local IP has changed to 192.168.1.27 from 192.168.1.20 which hoses up windows clients as they can't see it any more until samba is restarted. After a Samba restart Windows clients can see the server again.

The change in local IP takes place after about 1 day or so but is random so unpredictiable.





On the Router should I enable this "auto reserve" --I'm not sure what that means.

Finding IP address

Hello,

Thank you for writing to Microsoft Community Forums.

I suggest you to follow the steps mentioned below to find printer’s IP address:

1. Type Devices and Printers in the Windows search bar.
   
2. Select on the printer and click on
   Manage.
   
3. Click on the Ports tab.
   You will be able to find printer’s IP address under the ‘Ports’ tab.
   

Few printers also have a “Test print” option on the printer. When you print a test page from network printer, the page shows the IP address along with other details.

Note: If it is set on DHCP mode the IP address will constantly change.
The IP address is assigned automatically by your router using a protocol called DHCP.

Hope it helps.

Changing IP Addresses

Apologies' - Can not quite understand fully what you have written.

IP addresses at home are determined by your Internet Service Provider. Some are fixed IP, some are forever changing 'Dynamic IP'. Mine at my home is dynamic never changing unless I power off the modem for a couple hours or so. Its Lease renewal period
is actually every 2hrs but as long as its still seen during the 2nd hour it keeps same IP so its more or less renews every hour.

For me to actually have a Fixed internet IP that never changes, I'd have to make arrangements with my Internet service provider... and I can imagine they will want to charge me extra for that or change me to a business account at higher rates than standard
residential rates.

Local 'LAN' network IP can be fixed or dynamic too - dynamic is default & you generally would set it as static in your router or router/modem by assigning its network cards mac address to a particular IP outside the range of the dynamic router address range,
usually near the DHCP setting.

 

Assigning Static IP Address Range in a Router

yep, pretty much all.

for point #2 if you are having difficulty binding static IP in the router, it is ok to set static IP in the camera instead - just make sure you take a note on which IP is which camera so that you wouldnt put the wrong IP in the port forwarding.

am not sure what you meant. you don't need ddns to access the camera locally (from inside your LAN) *Confused
