sipcalc 1.1.0

Usage: sipcalc [OPTIONS]... <[ADDRESS]... [INTERFACE]... | [-]>

Global options:
  -a, --all                     All possible information.
  -d, --resolve                 Enable name resolution.
  -h, --help                    Display this help.
  -I, --addr-int=INT            Added an interface.
  -n, --subnets=NUM             Display NUM extra subnets (starting from
                                the current subnet). Will display all subnets
                                in the current /24 if NUM is 0.
  -u, --split-verbose           Verbose split.
  -v, --version                 Version information.
  -4, --addr-ipv4=ADDR          Add an ipv4 address.
  -6, --addr-ipv6=ADDR          Add an ipv6 address.

IPv4 options:
  -b, --cidr-bitmap             CIDR bitmap.
  -c, --classfull-addr          Classfull address information.
  -i, --cidr-addr               CIDR address information. (default)
  -s, --v4split=MASK            Split the current network into subnets
                                of MASK size.
  -x, --classfull-bitmap        Classfull bitmap.

IPv6 options:
  -e, --v4inv6                  IPv4 compatible IPv6 information.
  -r, --v6rev                   IPv6 reverse DNS output.
  -S, --v6split=MASK            Split the current network into subnets
                                of MASK size.
  -t, --v6-standard             Standard IPv6. (default)

Address must be in the "standard" dotted quad format.
Netmask can be given in three different ways:
 - Number of bits    [/nn]
 - Dotted quad       [nnn.nnn.nnn.nnn]
 - Hex               [0xnnnnnnnn | nnnnnnnn]

Interface must be a valid network interface on the system.
If this options is used an attempt will be made to gain the address
and netmask from the specified interface.

Replacing address/interface with '-' will use stdin for reading further
arguments.
