Thought I'd answer my own question on this one. The answer is to put another router into the home network. As long as this is on a different subnet mask and has its one connection set to the main router I can turn off DHCP and the server takes over issuing IP address to the network. There is an interesting video on YouTube by Peter Lloyd from memory that explains this in a lot more detail. I hope this helps somebody
Hello this one is confused me for many years and I've never found an answer. I have a router which gives out IP addresses I then also have have a 2012 server which also gives out IP addresses. My thinking behind this is all wireless devices so laptops mobile phones etc will pick up an IP address from the router. the server itself has a fixed 192 address. I've set the router to issue ip addresses 10 to 150  and the server 151 and above. What I find is the wired devices all get their IP addresses from the 10 to 150 range it appears 151 and above of only get issued if I switch the router off which obviously I don't want to do do. What is the correct way to configure what is effectively two DHCP servers on the same network Thanks
