       005    RPL_BOUNCE
              "Try server <server name>, port <port number>"

         - Sent by the server to a user to suggest an alternative
           server.  This is often used when the connection is
           refused because the server is already full.

       302    RPL_USERHOST
              ":*1<reply> *( " " <reply> )"

         - Reply format used by USERHOST to list replies to
           the query list.  The reply string is composed as
           follows:

           reply = nickname [ "*" ] "=" ( "+" / "-" ) hostname

           The '*' indicates whether the client has registered
           as an Operator.  The '-' or '+' characters represent
           whether the client has set an AWAY message or not
           respectively.

       303    RPL_ISON
              ":*1<nick> *( " " <nick> )"

         - Reply format used by ISON to list replies to the

       306    RPL_NOWAWAY
              ":You have been marked as being away"

         - These replies are used with the AWAY command (if
           allowed).  RPL_AWAY is sent to any client sending a
           PRIVMSG to a client which is away.  RPL_AWAY is only
           sent by the server to which the client is connected.
           Replies RPL_UNAWAY and RPL_NOWAWAY are sent when the
           client removes and sets an AWAY message.

              "<nick> :*( ( "@" / "+" ) <channel> " " )"

         - Replies 311 - 313, 317 - 319 are all replies
           generated in response to a WHOIS message.  Given that
           there are enough parameters present, the answering
           server MUST either formulate a reply out of the above
           numerics (if the query nick is found) or return an
           error reply.  The '*' in RPL_WHOISUSER is there as
           the literal character and not as a wild card.  For
           each reply set, only RPL_WHOISCHANNELS may appear
           more than once (for long lists of channel names).
           The '@' and '+' characters next to the channel name
           indicate whether a client is a channel operator or
           has been granted permission to speak on a moderated
           channel.  The RPL_ENDOFWHOIS reply is used to mark
           the end of processing a WHOIS message.

              "<nick> :End of WHOWAS"

         - When replying to a WHOWAS message, a server MUST use
           the replies RPL_WHOWASUSER, RPL_WHOISSERVER or
           ERR_WASNOSUCHNICK for each nickname in the presented
           list.  At the end of all reply batches, there MUST

           and it was an error).

         - Replies RPL_LIST, RPL_LISTEND mark the actual replies
           with data and end of the server's response to a LIST
           command.  If there are no channels available to return,
           only the end reply MUST be sent.

         - When sending a TOPIC message to determine the

           the topic is set, RPL_TOPIC is sent back else
           RPL_NOTOPIC.

       341    RPL_INVITING
              "<channel> <nick>"

         - When listing the 'invitations masks' for a given channel,

         - Reply by the server showing its version details.
           The <version> is the version of the software being
           used (including any patchlevel revisions) and the
           <debuglevel> is used to indicate if the server is
           running in "debug mode".

           The "comments" field may contain any comments about
           the version or further version details.

       352    RPL_WHOREPLY

       315    RPL_ENDOFWHO
              "<name> :End of WHO list"

         - The RPL_WHOREPLY and RPL_ENDOFWHO pair are used
           to answer a WHO message.  The RPL_WHOREPLY is only
           sent if there is an appropriate match to the WHO
           query.  If there is a list of parameters supplied
           with a WHO message, a RPL_ENDOFWHO MUST be sent
           after processing each list item with <name> being
           the item.

         - To reply to a NAMES message, a reply pair consisting
           of RPL_NAMREPLY and RPL_ENDOFNAMES is sent by the
           server back to the client.  If there is no channel
           found as in the query, then only RPL_ENDOFNAMES is

           message is sent with no parameters and all visible
           channels and contents are sent back in a series of
           RPL_NAMEREPLY messages with a RPL_ENDOFNAMES to mark
           the end.

       365    RPL_ENDOFLINKS
              "<mask> :End of LINKS list"

         - In replying to the LINKS message, a server MUST send

         - When listing the active 'bans' for a given channel,
           a server is required to send the list back using the
           RPL_BANLIST and RPL_ENDOFBANLIST messages.  A separate
           RPL_BANLIST is sent for each active banmask.  After the
           banmasks have been listed (or if none present) a
           RPL_ENDOFBANLIST MUST be sent.

       374    RPL_ENDOFINFO
              ":End of INFO list"

           registration.

       391    RPL_TIME
              "<server> :<string showing server's local time>"

         - When replying to the TIME message, a server MUST send
           the reply using the RPL_TIME format above.  The string
           showing the time need only contain the correct day and
           time there.  There is no further requirement for the
           time string.

         - The RPL_TRACE* are all returned by the server in

           whether it was sent by an operator or not.  There
           is no predefined order for which occurs first.
           Replies RPL_TRACEUNKNOWN, RPL_TRACECONNECTING and

           RPL_TRACELINK is sent by any server which handles
           a TRACE message and has to pass it on to another
           server.  The list of RPL_TRACELINKs sent in
           response to a TRACE command traversing the IRC
           network should reflect the actual connectivity of
           the servers themselves along that path.

       235    RPL_SERVLISTEND
              "<mask> <type> :End of service listing"

         - When listing services in reply to a SERVLIST message,
           a server is required to send the list back using the
           RPL_SERVLIST and RPL_SERVLISTEND messages.  A separate
           RPL_SERVLIST is sent for each service.  After the
           services have been listed (or if none present) a
           RPL_SERVLISTEND MUST be sent.

       251    RPL_LUSERCLIENT
              ":There are <integer> users and <integer>

              ":I have <integer> clients and <integer>
                servers"

         - In processing an LUSERS message, the server
           sends a set of replies from RPL_LUSERCLIENT,
           RPL_LUSEROP, RPL_USERUNKNOWN,
           RPL_LUSERCHANNELS and RPL_LUSERME.  When
           replying, a server MUST send back
           RPL_LUSERCLIENT and RPL_LUSERME.  The other
           replies are only sent back if a non-zero count
           is found for them.

       256    RPL_ADMINME
              "<server> :Administrative info"
       257    RPL_ADMINLOC1

       258    RPL_ADMINLOC2
              ":<admin info>"
       259    RPL_ADMINEMAIL
              ":<admin info>"

         - When replying to an ADMIN message, a server
           is expected to use replies RPL_ADMINME
           through to RPL_ADMINEMAIL and provide a text
           message with each.  For RPL_ADMINLOC1 a
           description of what city, state and country
           the server is in is expected, followed by
           details of the institution (RPL_ADMINLOC2)
