What is the version of Gluetun

Running version latest built on 2026-08-07T11:45:47.701Z (commit 7eed6ea) on Linux 6.12.74+deb13+1-amd64 (x86_64)

What's the problem

It appears that when a DNS query within the container timeout, the domain name leaks to the host in the form *.home.—for example, example.com.home., example.net.home., I'm not sure why, but after spotting numerous NXDOMAIN queries for *.home. in the host logs, I discovered they were originating from the gluetun container.
