Hi @LawP and welcome to the Community! 
We are delighted to have you here!
Thank you for asking the Community!
You’d like to be able to block and IP address for a dynamic IP address that’s changing constantly. Please let me know if that’s not the case.
I’d like to invite some of our Top Experts and some of our Community Members to this discussion: Hi @JRaygoza, @Ben_M and @FCorbaci do you know a workaround to help @LawP, please?
Thanks a lot and have a lovely day!
Best,
Bérangère
