networking howto wanted

[Robert Storey]

Other than a networking how-to, one thing I'd like to suggest is a great
little Perl script which will help you calculate network addresses. It's
called ipcalc.pl, and can be downloaded from here:

http://jodies.de/ipcalc.pl

If you just type ./ipcalc.pl, it will explain the basic usage. Hope this
helps.

=================================================
bob at sonic:~/program> ./ipcalc.pl

Usage: ipcalc [-n|-h|-v|-help] <ADDRESS>[[/]<NETMASK>] [NETMASK]

ipcalc takes an IP address and netmask and calculates the resulting
broadcast, 
network, Cisco wildcard mask, and host range. By giving a second
netmask, you 
can design sub- and supernetworks. It is also intended to be a teaching
tool 
and presents the results as easy-to-understand binary values. 

 
 -n    Don't display ANSI color codes
 -b    Suppress the bitwise output
 -c    Just print bit-count-mask of given address
 -h    Display results as HTML
 -help Longer help text
 -v    Print Version
 
Examples:

ipcalc 192.168.0.1/24
ipcalc 192.168.0.1/255.255.128.0
ipcalc 192.168.0.1 255.255.128.0 255.255.192.0
ipcalc 192.168.0.1 0.0.63.255
