"Not a valid IP address pattern" has appeared every time for several months, whenever I suggest a site for submission. What does this mean, please? I have tried submitting from several different locations and get the same response, to what otherwise seems to be a compliant to to the rules submission. And the site I am trying to submit is a normal www . com address. I have tried the search function in this section for this, btw, but nothing came up. Thank you.
