I had an issue with an old Access Point whose DHCP server set up the local domain suffix as accespointbrand.com, with no way to change it from GUI nor config file. Unfortunately the AP manufacturer didn’t renew the domain and it was squatted by an ad serving website. Every hare domain became subdomain.accesspointbrand.com So now and then I would get those ads when using wifi. I ended up changing the Access point.
