iphone – iOS 17 (presumably) has damaged OpenDNS filtering

I’ve a personal server working on my dwelling community that offers out DHCP addresses and makes use of OpenDNS as a DNS server so I can use its content material fitering.

AFAIK it is at all times labored OK, however I’ve seen at the moment that if I’m going to a website that needs to be blocked on each my iPhone and iPad the web page hundreds. Each Safari and Firefox present this drawback. It is doable that is linked to having been upgraded to iOS 17, however I do not examine this type of factor frequently in order that may be a whole crimson herring.

Right here is the bizarre half:

If I load a web page I can see within the logs of my DNS server that it is returning the corrrect handle ( is the OpenDNS blocked website touchdown web page):

Oct  2 11:32:57 dnsmasq[29667]: question[A] vnt.xhamster.com from
Oct  2 11:32:57 dnsmasq[29667]: forwarded vnt.xhamster.com to
Oct  2 11:32:57 dnsmasq[29667]: reply vnt.xhamster.com is

If I examine the DNS entry on my cellphone utilizing one thing just like the Ping Device app, I additionally persistently get a end result that matches the IP handle above.

So, the place is my browser getting the proper IP handle from? I’ve Apple Non-public Relay turned off, as that is recognized to intervene with these items. By default, “Restrict IP Tackle Monitoring” is on (it isn’t clear to me what the distinction is between this setting and the APR one), however even when I flip it off I get the identical drawback. Generally, the block works so it appears intermittent.

The place else can I look to see the place iOS is getting the proper IP handle from for these websites?

So as to add; blocking nonetheless works positive on my laptop computer (Home windows 11), and all OpenDNS checks counsel blocking is configured accurately, e.g. visiting internetbadguys.com.
