What about adding static IP address to DNS system of the router? https://von-hamster.ru/os/добавление-статических-адресов-в-роутере-локальный-dns-keenetic-os/ (Russian text, very short and simple to translate into English) Explanation: It works just like file "hosts" in windows. You add a line with IP address of the forexample1.com and name "forexample.com". The device that initiates a connection asks router "What is IP address of forexample.com?" The router will answer with the IP address of forexample1.com and thus the device connects to forexample1.com It goes without saying that the second website should give an understandable answer, that is an answer that the device would understand correctly:)

What about the straitforward solution? All the routers are connected by wire and have *different* SSIDs. Clients that are moving from one room to another just reconnect from one wifi network to another (automatically). It may take seconds or so every time you change room. If it does not fit (as I read in the 1st post) maybe proper geometrical positioning of routers (e.g. in the doorways) would help them to communicate via wifi to make stable mesh. I have 4 rooms and a common corridor just as your picture shows. I have only one router positioned in the middle of the corridor and it is OK. WiFi connection speed varies but signal is stable and never drops. Keenetic Giga II.
