Nothing about banned IPs.
By default, blocking an IP or IP range prevents users from those IPs from making edits, with or without an account, or creating accounts. Similarly, if an account is blocked, any IPs they've edited from recently get blocked as well.
All of these functions can be customized on a per-block basis; blocks on shared IP ranges are usually configured to allow account creation and logged-in edits.
