Fixed IP, changed after a while back to DHCP

[dverleysen_151162104025310]

Hello,


I have set my camera's IP addresses to fixed several times, but after a week or more, they change back to DHCP and receive a new IP address.
Other devices on my network do not have this issue. The NVR with one connected camera retains the fixed IP address, but the other three cameras connected to the home network keep changing back to DHCP instead of keeping the defined fixed IP address.

Is it something with the config or another setting that is wrong?

@dverleysen_151162104025310 Truly a puzzle. I had thought that DHCP is the process by which devices learn the address of DNS servers. No DHCP: no DNS. (My knowledge is not deep.)
Perhaps you could try specifying the DNS servers (even if you are happy using the router gateway IP, just hard code it).

I found setting Static IP on individual devices to be a chore. Most routers offer the capability to "assign" or "reserve" IP addresses by entering device MAC addresses in a table. The device thinks it is using DHCP (and it is), but every time it gets the same IP from the table.

@dverleysen_151162104025310 It's entirely possible to mix static IP and DHCP addressing schemes. Since the default DHCP address range is between 100 and 149 (unless you changed it ... check it out), you'll want to avoid all of the addresses between 192.168.1.100 and 192.168.1.149 when you're assigning static IP addresses. That leaves the ranges from 2-99 and from 150-254 wide open, which is usually plenty for most home networks. Or else disable the DHCP of the router and have fixed IP on all devices within the same lan.
