Resolving DNS server errors within your router.

Does anyone understand or have a way to resolve DNS name resolution errors. I have read online about changing DNS within the router however it can leave you exposed,

Not sure how that makes sense, exposed to what? a better performing DNS server that doesn't auto-redirect bad URLs to an ad-page?. 

 

DNS is DNS, and typically the built-in one from your ISP can be lack-luster and not even as secure as a service like 1.1.1.1 (Cloudflare) or 9.9.9.9 (Quad9 consortium).  If your router lets you change it's DNS forwarder just set it to one of those and you should be set.  Using a crummy ISP-run DNS doesn't make anything safer.

If you're having DNS resolution issues across your network then yes you can change your DNS server. No this wouldn't leave you exposed so long as you know what you're connecting to.

 

Really though the ISP provided DNS should be working just fine. If you can't connect to anything you may want to inspect your equipment. It's possible something's gone wrong, needs to reset or replaced.

 

Depends on exactly what's giving you resolution errors. One computer or all your computers.

Appreciate the quick response. Read online saying you could leave your self exposed to hackers, wanted to clarify on here. Thanks for the information

Not sure where you heard you could be "exposed" .... I havent used Comcast's DNS services in quite a few years. As they were known to be slow, plus Comcast does funny things with DSN requests Ive heard. Ive used Open DNS and Google DNS services. Open DNS is nice if you want to do some filtering, while its not 100% fool proof, its can be nice. I currently use Google DNS, its fast and works great.
