Flags

• Authority if the router is a directory authority
• BadExit if the router is believed to be useless as an exit node (because its ISP censors it, because it is behind a restrictive proxy, or for some similar reason)
• BadDirectory if the router is believed to be useless as a directory cache (because its directory port isn't working, its bandwidth is always throttled, or for some similar reason)
• Exit if the router is more useful for building general-purpose exit circuits than for relay circuits. The path building algorithm uses this flag; see path-spec.txt
• Fast if the router is suitable for high-bandwidth circuits
• Guard if the router is suitable for use as an entry guard
• HSDir if the router is considered a v2 hidden service directory
• Named if the router's identity-nickname mapping is canonical and this authority binds names
• Stable if the router is suitable for long-lived circuits
• Running if the router is currently usable
• Unnamed if another router has bound the name used by this router, and this authority binds names
• Valid if the router has been 'validated'
• V2Dir if the router implements the v2 directory protocol
