What should I do if the hotel’s IP address is insufficient?

Haha, I feel like you don’t even understand the concept~DHCP is used by hosts, but the problem you mentioned is essentially a routing problem.

First of all, I want to ask the question you mentioned. I feel that the "wireless router" you mentioned is just AP. If you really have 12 routers, there will be no problem of insufficient IP. What will you do? Routing can handle distribution.

If your main router and branch routers are in the same network segment (a switching environment), in this case, static routing will have the smallest load and is the simplest. If you know how to configure it, it will be very simple:

1. Turn off DHCP on the internal network of the main router, and set a static IP for the internal network gateway: X the same network segment (for example, 192.168.1.2-192.168.1.254), and then make a default static route (default gateway) on all wireless routers pointing to the gateway X (192.168.1.1) of the main router;

3 , open DHCP on the internal network of the wireless router, and open a separate network segment for each floor (for example, use 192.168.11.1--192.168.11.254 on the first floor, use 192.168.12.1--192.168.12.254 on the second floor, and so on), so that you can There are 253 host IPs in the building. I believe it is enough. If it is not enough, you can also change the network segment to 10.0.0.0 and use the IP as you like~

If your main router and branch router If it is not the *** network segment, then configure a routing protocol for the intranet. If it is not supported, configure routing hop by hop. For the intranet, use a branch router to configure DHCP.

Comrade, if you look at your "wireless router" and it cannot be used as a routing or default gateway, that means it is not a router at all! In other words, your intranet environment is in the *** network segment. The simplest way is to get a Class A intranet private address 10. The switching environment of the network is high-end enough. It is super simple to set up a VLAN and then allocate subnets~
