DNS Call to upgrade repositories every 30 seconds

[rickitaly]

Hello, i am new to opnsense, coming from pfsense since many years.
I setup everything, adding also AdGuard Home. I am on 24.7.8.
Since some days i notice that on AdGuard there are 6 dns req to firmware repo "mirror.dns-root.de" and to mimugmails repo "opn-repo.routerperformance.net".
Something like this.

Another relative newb here... I'm sorry I don't have an answer for you but I saw your post while also investigating the huge number of queries in my Unbound for:

opn-repo.routerperformance.net  (32% of total queries)
pkg.opensense.org (32% of total queries)

They each have 25 or so A and AAAA cache lookups every 30 seconds. Like you I would love to understand why this is necessary?
