### Description

#### What problem are you trying to solve?
A persistently named client has been created using two identifiers on the "Settings"/"Client Settings" page. When viewing the client ranking on the homepage, the IPV4 and IPV6 of the client are separate and not directly clear.
#### Proposed solution
Set an option to merge IPV6 and IPV4 data from the client.

I have only recently come into contact with Adguardhome, and these are some of my ideas for using it. I hope Adguardhome is more perfect.
