Some routers allow you to define an IP for a chosen mac-address. Use that and DHCP will keep that address for your server.

You could also set a DHCP range to e. Apr 5 '18 at 7: Michal B.: I agree and did it meanwhile.: Obtain the server's mac address. Observe which IPs the router assigns to computers eg. Start the server in DHCP. In the router panel, name it, basing on its mac address so that the router will remember it. Restart the network service.

Welcome to TechTarget's expert community for technology professionals.

JohnA JohnA Reservations are essentially self-documenting. Document it. Maybe even reserve a range for this. You would normally either: To expand on these options: Static IP address If you prefer to set a static address, you should check your router's default configuration to determine the block of addresses used for DHCP leases.

Thank you Liam for your very detailed and useful answer. After accessing the router's configuration, other issues arised that I added in the original message. OuzoPower I'm new to responding here so don't have enough rep to comment on the question. Your update shows your router is not providing the DHCP service. The setting is off on the router, and your Windows ipconfig output shows the DHCP service is provided from a device at That's where you'll find your DHCP configuration.

This also explains why the router shows the addresses as static and why DHCP assigned addresses are outside the range configured on the router. No Pi-Hole or similar thing as far as I know. Solution found: As I could not set DHCP ranges in the router but could register the mac address of the server in the router and then attribute to the server a fixed IP address that is far beyond the range that the router is naturally assigning to existing devices.

Thanks to the registration of the server's mac address, the router keeps it in memory and shows the server as missing when thus is off. For details, see my answer to Michal B. This solution seems working like a charm. OuzoPower That approach may work in the short term but how do you know that the address you have picked is outside the DHCP range? Many DHCP systems pick addresses at random from the available pool. At some point you will need to know what your DHCP configuration actually is, rather than estimating by observation! Your question asked about best practice.

I would start by visiting Journeyman Geek 6, 3 27 Monitor the DHCP closely and set leases that are long enough to be able respond to problems even after a long weekend. I like this approach as well. This way I can still access the servers even if the DHCP server takes the morning off or decides to start handing out invalid leases!

Using isc-dhcp-server this is required this is what my pi does, along with DNS caching, a fake domain for my LAN, and some traffic shaping for some wireless stuff. Unfortunately, I've seen browser based router config pages both factory and replacement that either require a reserved address to be in the dynamic pool Qippix Qippix 11 1.

This literally makes no sense.

I have asserted that if you use static, you haven't gauaranteed that clients can "always access it"Not at all. I've just asserted that I've mixed static and dynamic in my setup. Gaius I have asserted that if you use static, you haven't guaranteed that clients can "always access it". I'm sorry that doesn't make sense to you: I've also asserted that I've mixed static and dynamic in my setup: Sorry, but I must admin not understanding most of your answer.

Multicast address

As far as I know, DNS are domain name servers and are useful when you want to name servers, like when assigning domain names to web sites. As I don't need domain names, DNS appears me useless. Accessing the server is not an issue without DNS. See my answer to Michal B.
