IPInfo command line tool - online help

Usage: IPInfo [IPNET] [OPTION] ...
Show information on IPNET (NetMask, HostMask, Bits, BaseAddress ...)
Example: IPInfo
Example: IPInfo
            will result in a netmask with 16 bits set =
Example: IPInfo!5
            will result in smallest valid net holding at least
            5 addresses (including base and broadcast address),
            which in this case is a net of 8 IPs, resulting in
            a netmask of or a /29 net.
Example: IPInfo /27
            will show netmask, bits and IP count for a /27 net,
            which here is, 27 bits and 32 IPs.
Example: IPInfo !5
            will show netmask, bits and IP count for a net holding 5 addresses,
            which here is, 29 bits and 8 IPs.
Example: IPInfo *
            will show all IPs assigned to the current host.
Example: IPInfo 2
            will show second IP address only.
Example: IPInfo *!8
            will show all IPs assigned to the current host,
            faking all nets to a net holding 8 IP addresses (/29),
            which will result in displaying wrong masks for IPs that
            really do not have a /29 net assigned. A (suppressable)
            warning is printed on each IP whose mask gets faked!
Example: IPInfo */29
            same as *!8
Example: IPInfo 2/29
            like */29, while only IP 2 of the current host is displayed.

IPNET: [IP][/Mask|/Bits|!Count]
   IP:    valid IPv4 address, dotted decimals
          or omitted, then ignored,
             when missing, options default to -n -b -c, which is useful to get
             the netmask on a given number of IP addresses (e.g. IPInfo !16)
          or "*" which is replaced by all locally assigned IP addresses
             defaults to "" if no local IP assigned
             (e.g. IPInfo * -i lists all local IPs)
          or a decimal number N, which is replaced by the Nth locally
             assigned IP address
   Mask:  valid IPv4 Network Mask, dotted decimals
   Bits:  number of set bits in Network Mask, 0..32
   Count: number of IP addresses in network, rounded up to next 2^n
             definied as "Count := 2^(32-Bits)"


Alter display format:
   -nlf       suppress output of CR[-LF]
   -pau[se]   wait for ENTER keypress at end
   -par[am]   display parameters and options
   -bin[ary]  add "dotted binary" output to each IPv4 address/mask
   -zer[os]   dotted decimals with leading zeroes (e.g.
   -lab[els]  label each output information (see below)
                 is default on -all or on no options given, otherwise off
   -nol[ab]   suppress labels (when -lab defaults to "on")
   -now[arn]  suppress warning on */x, *!x, n!x and n/x (see examples)

Information to include in output:
   -inf[o]    show local network information, like "ipconfig -all" does
   -all       show complete information (default, except of -inf),
                 overrides all of the following "display" options;
                 shows base and broadcast, when Bits=32 (=host address given)
   -i         IP address
   -n, -m     (network) mask as given by /Mask, /Bits or !Count
   -h         host mask, derived from network mask
                 hostmask := !netmask
   -b         network bits, derived from network mask
                 netmask := !(2^(32-bits)-1))
   -a, -ba    network base address
   -r, -br    network broadcast address
   -c         count number of IP addresses in IPNET
                 count := 2^(32-Bits)
   -im        output of IP/mask (e.g.
   -ib        output of IP/bits (e.g.
   -bm        output of base/mask (e.g.
   -bb        output of base/bits (e.g.

ATTN: joining options like "-i -b -c" to "-ibc" is not allowed!
