network names of containers

[xxlbug]

Hello everyone,

 

I was using the docker container names as network addresses (e.g. mariadb-nextcloud instead of 172.x.x.x) for a long time with my custom br0 docker network. One of the previous Unraid updates OR adding pi hole to my network changed something in this regard and I can only use ip addresses now.

 

Why don't I just use static ip's? I think working with names is much more elegant in regard to service configuration and keeping tabs on what service is using which addresses is a hassle in my ever-growing homelab.

 

My network setup looks like this:

 

Does anybody know what I'm doing wrong or what I could check/change to have my desired behaviour back?
