99 <P>The undernet P10 protocol uses a scheme of "Numerics" to uniquenly identify
100 a client or server within the network. Each server has its own unique numeric
101 (0 -> 4095) and each client has its own numeric within that server (0->262,143).
102 <P>The numerics are encoded into a Base64 stream to maintain human readable
103 data flow and reduce the size of the messages. The Base64 character set
104 used in ircu is included below, this defines all valid characters allowed
105 in a Base64 numeric with "A" representing 0 and "]" representing 63.
107 <PRE><TT><FONT COLOR="#00007F">ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789[]</FONT></TT></PRE>
109 Server numerics consist of 2 characters, with the minimum, 0, being represented
110 by "AA", and the maximum, 4095, being represented by "]]". Client numerics
111 are 3 characters long, with the minimum, 0, being represented by "AAA",
112 and the maximum, 262,143, being represented by "]]]". The unique identifier
113 of a client on the network consists of a combination of both the server
114 and client numeric in the format SSCCC.
115 <P>As an example, consider a server "irc.undernet.org" which has a numeric
116 of 2, translating to "AC" in Base64. On this server exists a client, whom
117 has been allocated the numeric 63 (which translates to "AA]" in Base64).
118 Therefore, the unique identifier of this client on the network is "ACAA]".
119 From this, we can determine which server the message came from, aswell
120 as the client who sent it.
121 <P>These numerics are used to prefix every message issued on the stream
122 except for the initial "PASS" or "SERVER" message, which are not prefixed.
123 Therefore, every message that can be recieved from a server will consist
126 <PRE><FONT COLOR="#00007F">[NUMERIC PREFIX] [TOKEN] [DATA]</FONT></PRE>

132 <A NAME="chap2.2"></A><B><FONT SIZE=+1>2.2 Token Table</FONT></B>
133 <P>The following table lists all the acceptable messages, along with their
134 relevant "Token", which is used in the server<>server protocol. The
135 aim of tokenisation is to reduce the bandwidth used during network communication
136 by reducing the length of common message identifiers.

586 If the server being introduced has not yet successfully synced its
587 database with the network (Completed its net.burst - see 3.2), then the
