+1. Changed the default of X and Y (in item 2 below) to 27 and 20 respectively.
+24Mar23=======================================================================
+1. Restore perl regex version of is_ipaddr. This *should* allow windows
+ updates to work again.
+2. Added cmd entry rate limiting. If a user sends X commmands in Y secs then
+ they are disconnected without notice. The defaults are X
+ ($DXCommandmode::maxcmdcount) = 16 and Y ($DXCommandmode::cmdinterval) = 9.
+
+ These can be changed by the startup script.
+
+ These default values are set generously deliberately to allow certain user
+ programs to get with the program and reduce the number of cmds that they
+ issue on connection down to something reasonable. For instance, I cannot
+ see why things like name, qth, lat/long/QRA (amongst several other sticky
+ user attributes that only need to be entered once) are sent on every login.
+
+ These default values WILL reduce over time.
+23Mar23=======================================================================
+1. Fix DXCIDR brokenness introduced recently, speeded up DXCIDR::sort, allow
+ sh/badip 2a05:dfc7:402a::1 45.134.225.96 159.69.38.160 to test individual
+ IP address as well as show the default (of every badip).
+2. Speed up and be more strict with input for is_ipaddr(<ip address>).
+22Mar23=======================================================================
+1. Fix warning in DXUtil::difft.
+21Mar23=======================================================================
+1. Fix DXUtil is_ipaddr function which was accidentally included in previous
+ commit.
+2. Do not extract IP addresses to create routing info as default.
17Mar23=======================================================================
1. Try to nail down incoming PC92s that attempt to change the type of $myalias
or $mycall.
2. Do some housekeeping with the startup and finish debugging to make the
order of messaging more logical. Also disable some messaging caused by
other errors/circumstances causing various object handles disappearing.
+3. Make sure that $mycall and $myalias are upper case (and moan about it if
+ they aren't.

1. I am aware that there are windows nodes out there on mojo (brave, impetuous
that you are) and wget is not an easy option to download badip files. So,
