ipcalc

a cli tool for converting between decimal and binary versions of IPv4 and IPv6 addresses and do some operations on IP addresses, check features for more info.

SOON

usage

requirements

• make
• gcc or clang

installation

• initialization:

make init

• compiling and installing:

make install

• unistalling:

make uninstall

available options

-b, --bin	convert decimal to binary
-t, --type	network type: INTERFACE or NETWORK
-n, --net	get network address
-h, --help	print this help
--isnet		check if it is a network address
--isint		check if it is an interface address

Notes:

• -b, -n, and -t can be used multiple times in a single command

TODO

Fixes

• seg fault when using --bin with invalid ip version:

   ./build/ipcalc --bin=9 192.0.1.0

  and another one when using --isnet without -s:

   ipcalc --isnet 192.0.0.0

Document

• document: the 'core/ipv4.h' functions, ...
• document: the ipc_type() function

Makefile

• Makefile: add options: install and uninstall
• Makefile: organize the dependancy graph

Features

• feat: is network or interface ip address? (--isnet, --isint, --type*)
• feat: network address
• feat: broadcast address
• feat: usable host ip range
• feat: total number of hosts
• feat: number of usable hosts
• feat: subnet mask (for example '/16' <-> '255.255.0.0')
• feat: wildcard mask
• feat: binary ip (--bin)
• feat: ip class
• feat: CIDR notation (/24) of the subnet mask (255.255.255.0)
• feat: ip type: public or private
• feat: short notation, ex: 192.168.1.1/24
• feat: all possible addresses for the ip address
• feat: table of the number of hosts per subnet

Other

• use / instead of -s
• remove replacable fprintf() with log_err()
• make log_err() accept multiple arguments like printf() family
• solve all the warnings resulting from make
• make a script that remove comments from source code
• no comments script: deal with links, and other exceptions
• rename functions and variables
• use the belformat library
• add some examples to that README
• make an ip struct
• use getopt_long or getopt_long_only instead of getopt
• handle errors like a pro
• think about making the while loop in main as the following steps:
  1. check for option
  2. handle option
  3. log errors
• making some global options options subcommands, like --bin will be used without dashes (bin).
• provide some other optons like --time, --verbose, ... and use bitwise operators to select them
