Hi,

I have a Netgear router at my home. I have several devices that I want to connect to it with STATIC  IP addresses and not DHCP.

What do I use for the DNS? Since I have my internet through the cable company and the DNS can change, what is the best way to do this?

Thanks!

In TCP Properties, check get DNS address automatically. Now you will get it from your ISP (through the router).  Or you can set DNS addresses to (if you prefer): 4.4.4.1 and 4.4.4.2.

If I use a static IP it wants a static DNS, no option to select auto for DNS

You could also setup DHCP reservations on your NetGear router. That would allow them to get the DNS address should it change while still being able to always have the same internal private IP address such as 192.168.1.50 or whatever you choose.

The static IP address reservation for NetGear routers have had problems in several models in the past. Are such problems fixed now; and does the IP reservation work without problems now?

for a Static IP, use the following settings...


ip: 192.168.x.x or 10......
gateway     192.168.x.x  (internal ip address of your router)
DNS            192.168.x.x (internal ip address of your router)

As you say, your dns will change.   You internal DNS server address will never change.
Your public (internet ip address) is probably dynamic and can change in the future.

This will give you a problem when you try to connect from the internet to one of your static devices (by a nat rule on your router)....
