Frequent ping to

Hi there,

I noticed my desktop PC running Mint 19.1 is making a ping to approximately every 30 seconds. After a bit of sleuthing, I learned this was Apple's captive portal detection service running in Germany.

I blocked the DNS query at my pi hole, and the system switched to using the less alarming but still moderately alarming I captured the request in wireshark:

GET /hotspot-detect.html HTTP/1.1
user-agent: CaptiveNetworkSupport/1.0 wispr
accept-encoding: gzip,deflate
Connection: close


I do not, nor have I ever, owned an apple device or product, and I do not want my ethernet wired linux device pinging apple for captive portals every half minute (that's an order of magnitue higher than my next frequent DNS query).

Could you please help me diagnose which application is making the request, or explain to me why it would be doing this? If you could help me figure out how to trace the request back from wireshark that would be excellent because there are a few other DNS queries that I would like to investigate their origin.

Thank you!
