Have you ever come across that error that says “DNS lookup failed” or “DNS Server not responding” when using your smile, spectranet, ntel or Swift modem? Here is a solution that works. No we don’t do magic.
As mobile internet usage surpasses Desktop users, more and more people are coming online and there is bound to be issues. Today we would be talking on DNS which stands for Domain Name System Server, and it involves the translation of a web address into it’s original IP address.
Every website has it’s own unique IP address that the domain name translates to. There are many reasons you might want to change your DNS Server, reasons starting from better security system, speed of connection and other fantastic features a DNS Server might offer. If your ISP is having big issues with its DNS service and your connection is starting to get really annoying, it is high time you switch to a public DNS Server. Recently (Last week), i had an issue with my ISP, ntel, some of you would have seen my outcries on my twitter TL last week. They had a problem with their DNS Server and this was how i fixed it.
There are plenty of free to use DNS servers online and this is a good news.
A good example is Google Public DNS
– Google Public DNS IP addresses (IPv4) are as follows:
Primary address: 220.127.116.11
Secondary address: 18.104.22.168
– Google Public DNS IPv6 addresses are as follows:
Primary address: 2001:4860:4860::8888
Secondary address: 2001:4860:4860::8844
Another example is OpenDNS. See here.
– OpenDNS Public DNS IP addresses (IPv4) are as follows:
- Primary address: 22.214.171.124
- Secondary address: 126.96.36.199
I usually recommend Google Public DNS as it was created to provide users with a fast and secure DNS resolution. Google also promises that it wont be tampering with your data or whatsoever when using their public DNS.
How-to Change Your Router’s DNS Server.
