Danzuni Well, accessing the web through IP addresses is the second best solution. The whole construction of the Domain Name System (DNS) was invented to use easy-to-remember names instead. I know, you are self-contained in your LAN and you may not have registered a domain name for your computers. In such a situation you can invent a domain name! You have to be careful though, not to duplicate existing domain names nor to use reserved names for other purposes.
For example, look at the domain name moodlebox.home. The top-level domain 'home' is something ICANN has reserved and won't sell, hopefully. When devices get an IP address from a DHCP server, they most often get the address of a (or many) DNS server(s). MoodleBox runs a simple DNS server at its wireless interface, and that is what it gives as the DNS server to the devices connecting to its wireless network.
You can do the same in your ethernet LAN through your router/DHCP server - if it runs a simple DNS server, which they usually do. Configure its DNS to resolve moodlebox.home to the ethernet IP address of the MoodleBox. If you get it right all users will be calling the MoodleBox as moodlebox.home, from the MoodleBox wireless network and the ethernet network of the router.
