명령어 사용법
$ sipcalc --help
sipcalc 1.1.6
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, --classful-addr Classful address information.
-i, --cidr-addr CIDR address information. (default)
-s, --v4split=MASK Split the current network into subnets
of MASK size.
-w, --wildcard Display information for a wildcard
(inverse mask).
-x, --classful-bitmap Classful 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.
Report bugs to <simon@routemeister.net>.
