Sanrio Wiki:IP account
An IP account in a technical sense is not recognized as a user group on Special:ListGroupRights, however it falls under the (all) category. It refers to any account that is not a registered User (both IP accounts and registered users can perform basic acts on a wiki, such as reading and editing pages, although there are some advantages to having an account).
On the other hand, there is some more freedom in that edits can be made without using an account; and the IP account will be automatically generated, and users may change it, hide their real location using a VPN if they prefer. However, altering one's IP address after a ban to avoid the ban is strictly not allowed.
