If you reverse the entries, for example, and put 8.8.8.8 first - you will never make it to the internal DNS server and all internal lookups will fail. If the first server fails to find the entry you seek, it will simply return a failed response. Yeah that makes sense, I guess I was thinking that using an internal one would only check for records that existed on it, so if wasn't found on the internal one, that would be why the system would then go to the 2nd DNS entry, so didn't realize the internal one would then look it up.Ĭorrect, DNS doesn't work that way.
#Google dns servers mac windows
I just connected my iPhone to the network, ran a network utility app which shows my DNS is 192.168.1.3 as primary and 1.1 as secondary, but nslookup on there to can't resolve.Īm I missing something or doing something wrong? There's NO issue on any of my windows machines, they always ping and resolve it no problem. So this time it did work, and it has once before, but the issue is all day yesterday I had nothing, and if I connect my iPhone for example it does the same. So then I did nslookup and it worked this time showing: Got SERVFAIL reply from 192.168.1.3, trying next server I then did nslookup dynamics, and this time I got
#Google dns servers mac mac
So just now on my mac I did nslookup and it showed Server: 192.168.1.3 which is my DNS server and then it showed the address. Sorry so as I was writing this, I remembered I wanted to try nslookup first to see what things were doing. The issue though is that if I ping any of those servers "dynamics" "" "" etc, it all says it can't be resolved and icmp ping failed. The issue is that when my Mac, iPhone etc connects, they are assigned the IPs the same, and they also show DNS server as 192.168.1.3 as primary, with 192.168.1.1 as secondary. Also, if I ping, it resolves to 192.168.1.3, and if I disconnect the wifi and tether to my phone to be on a different network, pinging shows our external IP as expected. If I go to command line and do "ping dynamics" or "ping " etc, I get the expected results that it is resolving to 192.168.1.4. If I connect a Windows laptop or machine to the network, the DHCP server assigns it an IP no problem, and ipconfig shows the proper IP address, and the DNS servers as expected. On the server under DNS settings, if I go to my and view forwarding domains, I see A name records for dynamics, ad and so on. I then added a voip entry called "voip" to resolve to 192.168.1.5. The DHCP server on this machine is set with primary DNS at 192.168.1.3 and secondary 192.168.1.1. The AD DC computer name is "ad" and then I have a CRM server at 192.168.1.4 which is named "dynamics". As an example lets say my domain is just. I have an AD DC which has my DNS and DHCP on it, IP is 192.168.1.3 with my router 192.168.1.1. I thought I understood DNS and DHCP servers after reading and doing training but I'm having an issue. Hi everyone, kind of new at this but have a question.
