Editing Wikipedia with an IP address as your identifier is often less anonymous than editing with a normal account.

Why is this the case?

All of these provide mechanisms for curious individuals to determine where you live or who you are.

Second-class treatment of IP address editors

Some registered Wikipedia editors and administrators treat IP address editors as (at best) unwelcome party-crashers or as potential vandals. Some ignore the opinions or revert the edits of IP address editors simply because they are "anonymous". There is no Wikipedia policy which supports this treatment, and there are several long-term and constructive Wikipedia editors who edit solely under a fixed IP address.

The treatment of IP address editors as second-class editors is counter to Wikipedia policy and the spirit of anyone-can-edit collaboration.
