Actual Behaviour:

There're still only devices IP address on Pi-hole Admin Console.

Conditional forwarding is not successful with some routers.

As an alternative, you can use your Pi-Hole to serve DHCP and it will obtain client information directly from the clients, and conditional forwarding won't be required.

How do I use Pi-hole's built in DHCP server (and why would I want to)?

Using Your Existing Router For Network-wide Ad Blocking You might not need to use Pi-hole's DHCP server: In many home environments, your router also functions as your DHCP server. In this case, you can often set Pi-hole to be the DNS server for your network clients in the router's DHCP (or LAN) settings page, which allows all of your network clients to block ads simply by connecting to the network. Setting it up this way is also what makes Pi-hole very powerful for network-wide ad blocking. …

So can there be two DHCP servers in a network?

Yes, but.

1. They need to be on non-overlapping ranges so each doesn't try to provide the same IP address to different clients.

2. There may still be problems when leases are renewed. Many users have reported no problems with two DHCP servers on non-overlapping ranges, but there is a possiblity you may have problems.
