This has come up enough it seems worth noting for this U.S. Thanks Giving Holiday. The concept of public Domain Name Service (DNS) is not new, but worth discussing both the merits and pitfalls.  We’ve discussed DNS here quite a bit over the years, for a prospectus [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14].

There are a few (this is not an endorsement *quickly looks around for legal counsel and dodges them*) good services around that are known. Some ones worth mentioning that seem to be well maintained and have a free service for personal use:

Symantec

https://dns.norton.com/configureRouter.html

OpenDNS

https://store.opendns.com/setup/#/familyshield

Google DNS

https://developers.google.com/speed/public-dns/?hl=en

This might be a good way to also help out those friends and family that *sarcasm* inevitably call us for Information Technology support, and help make them a ‘little bit’ better off. Your mileage may vary… 

To those in the U.S., or abroad, or whomever is celebrating Thanks Given, have a happy one!
