DNS resolution

Can anyone explain how the DNS gets set?

My situation is Mac based:

iPhone, iPad no problem.

Mac airBook, MacBook Pro running OSX 10.14.1 problem

HP Envy 5640 printer problem.

I've got round the issue by hard coding addresses into the lap tops but where is the problem?

Where is the DNS address created when I have the machines configured for "Confighure IPv4 Automatic"?

Agents are: 

laptop <-> Hub3 <-> Downstream

Clearly there is negotiation taking place but where do I need to focus for a resolution?

Re: DNS resolution

DNS addresses are set on the virgin hub which is applied to your devices via DHCP.

what issue are you actually having>

Re: DNS resolution

The DNS returned is 10.0.1.1 and I cannot access the internet with this address

The Router address is also set to 10.0.1.1

When I run Network diagnostics the ping of 10.0.1.1 fails.

I had been Renewing the DHCP Lease and sometimes it would give a valid IPv4 address set but often this did not "stick". As I looked at the network screen it would revert to 10.0.1.1

I have implemented a work around of taking DHCP out of Automatic and set it to Manual. Thus hard coding the addresses. Not really happy with this solution.

I cannot get VM to accept that the problem lies within their Hub3.

Re: DNS resolution

on your PC/laptop/phone etc the DNS address shown will be your hub/router - that is correct.
the DNS IP addresses your hub uses will be set on the hub.

again - what is the problem you are having? you haven't expained what the actual problem is.
so far i can't see any problem with what you have said.

Re: DNS resolution

The problem is that I cannot connect to the internet with the addresses supplied by the Hub3.

Re: DNS resolution

you can on your ipad and iphone though when connected to your virgin hub?
if yes then there is nothing wrong with your virgin hub or connection.

the problem seems to be on your macbook.
if you have played about with the network settings on your macbook then i would advise resetting them back to defaults.

Re: DNS resolution

I totally agree with your advice. However, when I use the "default" settings and let the Hub3 supply the address I cannot access the internet.

I will continue to try using the default but it is very frustrating.

Re: DNS resolution

the issue appears to be with your macbook config by the sounds of it.
to be 100% sure you could factory restore the virgin hub, but if the iphone and ipad are working then the issue is not with the virgin hub or the DNS/DHCP settings on the hub.

also, if you hub is giving out 10.0.1.x IP addresses then you must have already changed something on the virgin hub, as by default it would be 192.168.0.x IP addresses. hence why the suggestion that you factory restore the virgin hub.

Re: DNS resolution

The Addresses on the iPad is 198.168.0.11 and not 10.0.1.1

When I use this form of address it works on the MacBook but when I let the hub return an address (10.0.1.1) it fails.

I can request "Renew DHCP Lease" and the hub will reset the values.

I keep renewing the lease until it gives me a value in the form 198.168.0.nn then I can get on the internet.

I assume that the hub is "rejecting" my request to connect by returning an invalid address but have no idea what is causing the problem.

Re: DNS resolution

By factory restore undo you mean hold in the "reset" button for 30 seconds?

I have not changed anything on the hub. Although VM support may have done so.
