 ## Create address maps
 
 To avoid any errors if you have [static IPs](/byoip/concepts/static-ips/), Cloudflare creates an address map during the static IP onboarding process, meaning you cannot create a new address map with your static IPs. You may only edit the Cloudflare-created map and add or edit your zones within the existing map.
