3.2.3 SILC Server Ports
-SILC uses currently TCP port 334 on SILC network. However, this is not
-official port assigned for SILC. Official port has been requested by
-the IANA.
+Following ports has been assigned by IANA for the SILC protocol:
+
+.in 10
+silc 706/tcp SILC
+silc 706/udp SILC
+.in 3
If there are needs to create new SILC networks in the future the port
-numbers must be officially assigned by the IANA. Most convenience case
-would be to assign port numbers upwards from 334.

Server on network above privileged ports (>1023) should not be trusted
as they could have been set up by untrusted party.

+3.12 SILC Version Detection
+
+The version detection of both client and server is performed at the
+connection phase while executing the SILC Key Exchange protocol. The
+version identifier is exchanged between intiator and responder. The
+version identifier is of following format:
+
+.in 6
+SILC-<protocol version>-<software version>
+.in 3
+
+The version strings are of following format:
+
+.in 6
+protocol version = <major>.<minor>
+software version = <major>[.<minor>[.<build>]]
+.in 3
+
+Protocol version may provide both major and minor version. Currently
+implementations must set the protocol version and accept the protocol
+version as SILC-1.0-<sotware version>.
+
+Software version may provide major, minor and build version. The
+software version may be freely set and accepted.
+
+Thus, the version string could be, for example:
+
+.in 6
+SILC-1.0-1.2

+ nicknames in the SILC. The <count> option maybe given to narrow
+ down the number of accepted results. If this is not defined there
+ are no limit of accepted results. The query may also be narrowed
+ down by defining the server name of the nickname.
