block specific website addresses

OP's question concerned your Panoramic router.  I noticed "Panoramic" is mentioned zero times in this article.  I reads like a promo for Google.  Let's have Microsoft, Apple, Google and Amazon track our kids.

Crystal S.,

I concur with Bruce's reply. I have read the "parents ultimate guide parental controls". The sum of which is "go use a third party software", when what I asked for was the standard URL blacklist available on every router ever. Where is this option on the recommended Cox router?

I'd like to note that I researched, and purchased, a Cox approved router ready to go when the installation tech arrived. He convinced me with dire tones that I should just let him install the Cox router that comes with a rental fee. I now come to find out that standard router features are hidden or not available (???!!!).

Again, and more specifically, turning on parental controls through the Cox wifi app or by logging into cox.wifi.com blocks Fortnite and YouTube, which I want to allow. I want to block e.g. Liveleak for my children.

I understand the converse, which is that I might not/could not know of all the websites to block and so I should allow Cox's Parental Controls to do my parenting for me. So then how do I do the inverse: turn on parental controls, and then "whitelist" Fornite and Youtube and etc....?
