Filter and enrich a list of subdomains by level

dsieve

Take a single domain or read an input file and extract unique parent domains, enrich subdomains, filter subdomains by level, or find out which subdomains have the most number of sub-subdomains (or sub-sub-subdomains or sub-sub-sub...). Dsieve supports any format of URL, with or without protocol, port, path, parameters.

Usage

  -f string
    	Filter domain level. Use python slice notation to select range.
    	Example input: foo.bar.baz.tld
    	  -f 3      bar.baz.tld
    	  -f 3:     bar.baz.tld, foo.bar.baz.tld
    	  -f 2:4    baz.tld, bar.baz.tld
    	  -f :3     tld, baz.tld
  -i string
    	Input url or domain
  -if string
    	Input file path, one url/domain per line.
  -o string
    	Output file path, optional
  -top int
    	Only consider top X subdomains of a certain level and return all their subdomains

Domains can be passed through stdin as well.

Example

test.txt
a.foo.target.com
b.foo.target.com
c.foo.target.com
a.bar.target.com
b.bar.target.com
a.baz.target.com
# All levels by default
$ dsieve -if test.txt
a.foo.target.com
foo.target.com
target.com
b.foo.target.com
c.foo.target.com
a.bar.target.com
bar.target.com
b.bar.target.com
a.baz.target.com
baz.target.com

# Level 2, the main domain
$ dsieve -if test.txt -f 2
target.com

# Level 3, one level above the main domain
$ dsieve -if test.txt -f 3
foo.target.com
bar.target.com
baz.target.com

# Levels 2 and above, main domain and all its subdomains
$ dsieve -if test.txt -f 2:
a.foo.target.com
foo.target.com
target.com
b.foo.target.com
c.foo.target.com
a.bar.target.com
bar.target.com
b.bar.target.com
a.baz.target.com
baz.target.com

# The top one level 3 subdomain with the highest number of sub-subdomains
$ dsieve -if test.txt -f 3 -top 1
foo.target.com

# The top two level 3 subdomain with the highest number of sub-subdomains
$ dsieve -if test.txt -f 3 -top 2
foo.target.com
bar.target.com
