Yes, my iPhone has internet. When I key the IP into Safari, it continues to say the the page cannot be found.
However, I found something by accident. After several dozen attempts at keying in the IP into my phone and a couple others, I texted the IP to a friend with an iPhone and it worked. I found that after the IP was keyed into a text app and then copy and paste it into Safari, the browser then treats it as a web address and opens the page.
I do not know why but it seems to make a difference to Safari in my phone.
