I do not have dedicated ip address on the Internet I use. So if I use cloudfare then what would my IP address block? Because my ip address is changing every day. Since I am an admin, would I have any problem?
We need to clarify some things first:
Meaning your internet at home or at the office? Dynamic IPs are most common, you’ll get a new one after each, probalby every 24h, disconnect. Is it this what you mean?
Guessing: you want to host a website behind that dynamic IP?
If so, I need to answer
with: yes, but:
It’s possible to update DNS records with DNS-o-Matic for example everytime your IP address changes.
It’s all guessing since your question is unclear to me.
