My area is “owned” by Comcast, now Time Warner, when it comes to cable TV and Internet services. Unfortunately, their DNS servers have become unreliable numerous times over the years.
With that in mind, I’d like to share memorable IP addresses of DNS servers that I use that I have found to be very reliable. Thanks to Level 3 for letting the public use them.
They are:
- 4.2.2.1
- 4.2.2.2
- 4.2.2.3
- 4.2.2.4
- 4.2.2.5
- 4.2.2.6
You can definitely make use of them for all your DNS queries/needs. In fact, running a simple ICMP ping test resulted in Level 3’s DNS servers out-performing Comcast/Time Warner’s DNS servers.
