I recently regraded my LAN and in doing so forgot to have my WeeWX machine use external DNS. It was pointed to my pihole DNS servers.
Because of that, I see that the WU update is not very well behaved. It seems to call for a new DNS lookup every time it fires. With rapid fire on, that is 85000+ DNS calls daily! rtupdate.wunderground.com 85026 wx.lan 87934 That number of lookups raised warnings on my pihole machines, they want more resources to handle the high volume of calls. I reconfigured the WeeWX machine to use external DNS, but the issue is just being pushed elsewhere. Nothing on my network makes that many DNS lookup calls, not even close. Every OS I'm aware of has a DNS cache, WeeWX doesn't seem to use it though. However, WU has a TTL of only 60 seconds, but that is still around 24X less.
