**Problem with Beta 5.0:**

I have a client that requires special blocking rules. The problem is that it's an android device using IPv6 which means no DHCPv6, privacy extensions, and zero control over what it's doing. I can configure a client easily for the ipv4 address but it ends up using ipv6 and going around my custom rules and since the privacy address is changing I can't manually configure a rule for it. I do, however, have DNS names for the privacy addresses (I'm not 100% sure how because I thought that dnsmasq ra-names didnt work for privacy addresses but I can see them all in the client list with the right names).

Is there any way to configure special handling for this client, or of not can I request that clients be optionally configured to any connection that is using a particular DNS name?

Defining clients by hostname is possible in this experimental branch:

> [@Feedback for "Allow defining clients by their MAC address, host name and networking interface"](https://discourse.pi-hole.net/t/feedback-for-allow-defining-clients-by-their-mac-address-host-name-and-networking-interface/32324):
>
> Started this topic to provide feedback to the new feature allowing clients to be defined by MAC address. I switched to the branches (core still master) by pihole checkout ftl new/mac\_clients pihole checkout web new/mac\_clients And flushed network table afterwards. Important First thing I noticed in Group management/Clients Known Clients now only contain clients with known MAC, no IPs are listed anymore (I have devices on other Vlans so IP would still be handy).
