Client proxy type.

Defaults to? when an IP address is not known to be a proxy or VPN. Otherpossible values are:

• anonymous - IP address of client is not available. Includesservices that change location to beat DRM, TOR points, temporary proxies,and other masking services.
• aol - Proxied users from an AOL proxy.
• blackberry — This new value will identify an IP address owned byResearch In Motion (RIM), the company responsible for Blackberry mobiledevices. All Blackberry users go through a centralized proxy location andthus cannot be accurately geo-targeted.
• consumer-privacy - A group of users who are using a consumer serviceto proxy their traffic (e.g., iCloud Private Relay).
• corporate - Generally considered harmless, but location can be aconcern. Groups of users that are proxied through a centrallocation or locations, and thus share a single network-apparent IP address.
• edu - Proxied users from an educational institution.
• hosting - Address belongs to a hosting facility and is likely to be aproxy as end users are not typically located in a hosting facility.
• public - Multiple users proxied from a location allowing public internetaccess.
• transparent - IP address of client is available via HTTP headers,though the value is not necessarily reliable (e.g., it can be spoofed).
• ? - Not determined to be a proxy.
