CIDRoutputmodes:--optimize--combine--merge--union-J
> MERGE mode (the default)
Returns all IPs found on all files. The resulting set is sorted.
--common--intersect
> COMMON mode
Intersect all files to find their common IPs. The resulting set is sorted.
--except--exclude-next
> EXCEPT mode
Here is how it works: (1) merge all files before this parameter (ipset A); (2) remove all IPs
found in the files after this parameter, from ipset A and print what remains. The resulting set
is sorted.
--diff--diff-next
> DIFF mode
Here is how it works: (1) merge all files before this parameter (ipset A); (2) merge all files
after this parameter (ipset B); (3) print all differences between A and B, i.e IPs found is either
A or B, but not both. The resulting set is sorted. When there are differences between A and B,
iprange exits with 1, with 0 otherwise.
--ipset-reduce PERCENT
--reduce-factor PERCENT
> IPSET REDUCE mode
Merge all files and print the merged set, but try to reduce the number of prefixes (subnets)
found, while allowing some increase in entries. The PERCENT is how much percent to allow increase
on the number of entries in order to reduce the prefixes (subnets) (the internal default PERCENT
is 20). Use -v to see exactly what it does. The resulting set is sorted.
--ipset-reduce-entries ENTRIES
--reduce-entries ENTRIES
> IPSET REDUCE mode
Allow increasing the entries above PERCENT, if they are below ENTRIES (the internal default
ENTRIES is 16384).
CSVoutputmodes:--compare
> COMPARE ALL mode
Compare all files with all other files. Add --header to get the CSV header too.
--compare-first
> COMPARE FIRST mode
Compare the first file with all other files. Add --header to get the CSV header too.
--compare-next
> COMPARE NEXT mode
Compare all the files that appear before this parameter, to all files that appear after this
parameter. Add --header to get the CSV header too.
--count-unique-C
> COUNT UNIQUE mode
Merge all files and print its counts. Add --header to get the CSV header too.
--count-unique-all
> COUNT UNIQUE ALL mode
Print counts for each file. Add --header to get the CSV header too.
Controllinginput:--dont-fix-network
By default, the network address of all CIDRs is used (i.e., 1.1.1.17/24 is read as 1.1.1.0/24):
this option disables this feature (i.e., 1.1.1.17/24 is read as 1.1.1.17-1.1.1.255).
--default-prefix PREFIX
-p PREFIX
Set the default prefix for all IPs without mask (the default is 32).
ControllingCIDRoutput:--min-prefix N
Do not generate prefixes larger than N, i.e., if N is 24 then /24 to /32 entries will be generated
(a /16 network will be generated using multiple /24 networks). This is useful to optimize
netfilter/iptables ipsets where each different prefix increases the lookup time for each packet
whereas the number of entries in the ipset do not affect its performance. With this setting more
entries will be produced to accomplish the same match. WARNING: misuse of this parameter can
create a large number of entries in the generated set.
--prefixes N,N,N, ...
Enable only the given prefixes to express all CIDRs; prefix 32 is always enabled. WARNING: misuse
of this parameter can create a large number of entries in the generated set.
--print-ranges-j
Print IP ranges (A.A.A.A-B.B.B.B) (the default is to print CIDRs (A.A.A.A/B)). It only applies
when the output is not CSV.
--print-single-ips-1
Print single IPs; this can produce large output (the default is to print CIDRs (A.A.A.A/B)). It
only applies when the output is not CSV.
--print-binary
Print binary data: this is the fastest way to print a large ipset. The result can be read by
iprange on the same architecture (no conversion of endianness).
--print-prefix STRING
Print STRING before each IP, range or CIDR. This sets both --print-prefix-ips and
--print-prefix-nets .
--print-prefix-ips STRING
Print STRING before each single IP: useful for entering single IPs to a different ipset than the
networks.
--print-prefix-nets STRING
Print STRING before each range or CIDR: useful for entering sunbets to a different ipset than
single IPs.
--print-suffix STRING
Print STRING after each IP, range or CIDR. This sets both --print-suffix-ips and
--print-suffix-nets .
--print-suffix-ips STRING
Print STRING after each single IP: useful for giving single IPs different ipset options.
--print-suffix-nets STRING
Print STRING after each range or CIDR: useful for giving subnets different ipset options.
--quiet
Do not print the actual ipset. Can only be used in DIFF mode.
ControllingCSVoutput:--header
When the output is CSV, print the header line (the default is to not print the header line).
ControllingDNSresolution:--dns-threads NUMBER
The number of parallel DNS queries to execute when the input files contain hostnames (the default
is 5).
--dns-silent
Do not print DNS resolution errors (the default is to print all DNS related errors).
--dns-progress
Print DNS resolution progress bar.
Otheroptions:--has-compare--has-reduce
Exits with 0, other versions of iprange will exit with 1. Use this option in scripts to find if
this version of iprange is present in a system.
-v
Be verbose on stderr.
Gettinghelp:--version
Print version and exit.
--help-h
Print this message and exit.
