DNS (Domain Name System) is like the phone address book for the Interwebs, translating human-friendly computer hostnames into IP addresses. For example, a domain name such as www.example.com translates to the addresses 192.0.32.10 (IPv4) and 2620:0:2d0:200::10 (IPv6).
Sometimes our ISP's DNS resolution service may be overwhelmed by the query requests it gets, so using a third party resolution service provider would be a great alternative.
Here are my favorite alternative DNS resolution services:
- DynDNS
- 216.146.35.35
- 216.146.36.36
- Google Public DNS
- 8.8.8.8
- 8.8.4.4
- OpenDNS
- 208.67.222.222
- 208.67.220.220
