Hi jmed999,

 

Please do make sure that you have the correct DNS settings under Configuration Tab | Network Settings. If you have configured your ISY with a static IP address, you might want to try DHCP or DHCP reservation since, some routers, do not allow DNS queries through if the IP is not assigned by them.

 

With kind regards,

Michel

Hi jmed999-

 

How do I know what the correct DNS settings should be?

 

How do I know if I have a static IP address?

 

What is a DHCP reservation?

 

Thanks for your help!

 

The correct DNS settings are usually provided by your ISP but you can use either: 8.8.8.8 or 4.2.2.2 which are public DNS servers. I suspect that you are set up for DHCP addressing since you are not familiar with Static addressing or DHCP reservation.

 

DHCP is a Protocol/process used by network devices to Dynamically Configure themselves with the assistance of a Host (your router or a standalone DHCP server). "Dynamic Host Configuration Protocol". When a client device is powered up, it looks for a DHCP server on the network and if found, asks for IP Address, Subnet Mask, Gateway address and DNS addresses to configure itself with.

 

DHCP reservation at the router simply reserves a specific IP address for a device so when that device auto configures, it always gets the same IP address from the DHCP server. This is ALMOST a static address as it always is the same.

 

Static addressing is when you configure the device by hand and disable its DHCP feature. You must provide valid addresses for IP, Subnet, Gateway and DNS and ensure that the IP address does not conflict with any other devices on your network.

 

DNS - Domain Name Service - Is basically a database of domain/machine names with their associated IP addresses. Anytime you call a server by name, google.com for instance, DNS is used to look up the IP address of the server before it can be accessed. Your ISP will usually have 2 or more DNS servers for their customers to use. Quite often, consumer grade routers will advertise themselves as DNS servers on your network via DHCP and pass DNS requests upstream to your ISP.

 

I hope this helps.
