Check Website Resolves?

[peaches017]

Is there any script out there that can quickly check if a website is resolving?

I need to input a list of domains in .txt format and it should tell me:

Google.com resolves
SampleName.com doesn't resolve

I would be willing to buy this script or pay to have it coded.

I just wrote this now.

Cba to sort out port 443 too. Simple change if you want to do it.
