Published Router Info
=====================
+Capabilities
+------------
+
+As of release 0.9.50, the "caps" option is supported in NTCP2 addresses,
+similar to SSU. There are two capabilities defined:
+
+4: Indicates outbound IPv4 capability.
+If an IP is published in the host field, this capability is not necessary.
+If the router is hidden, or NTCP2 is outbound only, '4' and '6' may be combined in a single address.
+
+6: Indicates outbound IPv6 capability.
+If an IP is published in the host field, this capability is not necessary.
+If the router is hidden, or NTCP2 is outbound only, '4' and '6' may be combined in a single address.
