Format character	Description
m	MAC address
i	IPv4 address
x	IPv6 address
X	IPv6 full address
n	Number
%	% character itself

Number specifier can be prefixed by padding length, such as %10n. If padding length starts with 0, 0 is used as padding character. Otherwise, space ( ) is sued as padding character.

Argument

MAC address

MAC address can be specified as colon separated HEX string or just a number.

$ macipr %m aa:bb:cc:dd:ee:ff
aa:bb:cc:dd:ee:ff

$ macipr %m 0
00:00:00:00:00:00

IPv4 address

IPv4 address can be specified as dot separated digits or just a number.

$ macipr %i 192.168.0.1
192.168.0.1

$ macipr %i 180000000
10.186.149.0

IPv6 address

IPv6 address can be specified as colon separated digits or just a number.

$ macipr %x ::1
::1

$ macipr %x 100000000000000
::5af3:107a:4000

If %X specifier is used, IPv6 address is displayed in full address format.

$ macipr %X ::1
0000:0000:0000:0000:0000:0000:0000:0001

$ macipr %X 340282366920938463463374607431768211455
ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff

Number

$ macipr %n 12345
12345

$ macipr :%5n: 123
:  123:

$ macipr :%05n: 45
:00045:

Multiple addresses

$ macipr "%m, %i" 0 192.168.0.1
0:00:00:00:00:00, 192.168.0.1

Range

Start-end range

This type of range specifies start and end addresses with hyphen (-) separator. Range includes both start and end addresses. End address can be less than start address.

$ macipr %m 0-5
00:00:00:00:00:00
00:00:00:00:00:01
00:00:00:00:00:02
00:00:00:00:00:03
00:00:00:00:00:04
00:00:00:00:00:05

$ macipr %i 192.168.1.1-192.168.0.254
192.168.1.1
192.168.1.0
192.168.0.255
192.168.0.254

Offset range

This type of range specifies start address and offset from it with plus (+) separator. Offset should be a number. If offset is prefixed by minus -, it represents a negative number.

$ macipr %m 01:02:03:04:05:06+3
01:02:03:04:05:06
01:02:03:04:05:07
01:02:03:04:05:08
01:02:03:04:05:09

$ macipr %i 172.16.0.1+4
172.16.0.1
172.16.0.2
172.16.0.3
172.16.0.4
172.16.0.5

$ macipr %i 10+-9
0.0.0.10
0.0.0.9
0.0.0.8
0.0.0.7
0.0.0.6
0.0.0.5
0.0.0.4
0.0.0.3
0.0.0.2
0.0.0.1

Multiple ranges

If multiple ranges are specified, printing continues for the longest range. Shorter ranges are looped as many times as necessary.

$ macipr "%m, %i, %i" 0+9 192.168.0.1 10.0.0.1-10.0.0.5
00:00:00:00:00:00, 192.168.0.1, 10.0.0.1
