DNS with iOS
-
Ok.. So if your clients are pointing to pihole for dns, where does pihole point to?
and
which dns you want to query mine was showing a weird entry.
What was your client pointing too?
-
@johnpoz the upstream for the piholes are the pfsense router.
-
Ok... I have a sim setup.. where pfsense then resolves.
So now that your clients are pointing to your pihole your working fine???
which dns you want to query mine was showing a weird entry.
What was this weird entry??
-
look in the 3rd image i posted of the he.net app. You can see for nameserver entry it lists
(defaults: , ,10.0.0.9)
correct it looks like (default: 10.0.0.9, 10.0.0.10,) -
Are other dhcp clients getting it correctly? Sniff the dhcp offer, does it list them both correctly..
I run ios on my phone, my wifes phone and tablet... Never seen any issues.. I do the same thing hand dhcp clients my pihole IP..
-
yes the dhcp offer and the router advertisement show the correct dns servers.
-
well than - look to your clients...
-
yeah i am, i was just hoping someone had seen this before. The people in this forum are a lot smarter than most.
-
Nope never seen such a thing... Been using iphone and ipad with pfsense for like ever..
-
Mmm, that does seem odd. Do the affected clients always show that? It could just be a display issue with the app.
I've not seen anything like that either.

@stephenw10 I also thought it could just be a display issue. But performance was bad when i set dns to automatic, and when i set it to manual, the performance was good and the display was correct.
Its seems like ios is getting/parsing and blank entry for dns, that eventually times out and it moves on to the next server in the list which is successful.
-
What version of ios are you running?
What happens if you set your dhcp server to just 1 IP?
-
12.2
-
And you have multiple devices doing this?
What does it look like under automatic? Do you have blank lines... Not the HE display, the normal wifi little i button when your connected.
-
Thats the 4th screen shot i posted, under automatic it look completely normal
-
What if you just turn off IPv6... You sure HE not just able to show the really long IPv6 addresses..
-
sure i can try.
But that wouldnt explain why it takes me less than a second eyeballing to to get a dns entry when it is set to manual in ios. and i just counted 8 seconds when it was set to automatic. Same domain each time that would be cached by the upstream.
Either way this is clearly not a pfsense issue but an iOS.
-
well when you manually set it only going to do ipv4?
Turn off ipv6.. Does that make your issue go away?
With ipv6 still off, set ipv4 to only 1 dns.. You sure this dns is working ;)
