asnmap -a AS45596 -silent
asnmap -i 100.19.12.21 -silent

JSON Output

asnmap by default displays CIDR range, and all the information is always available in JSON format, for automation and post processing using -json output is most convenient option to use.

echo hackerone.com | ./asnmap -json -silent | jq
{
  "timestamp": "2022-09-19 12:14:33.267339314 +0530 IST",
  "input": "hackerone.com",
  "as_number": "AS13335",
  "as_name": "CLOUDFLARENET",
  "as_country": "US",
  "as_range": [
    "104.16.0.0/14",
    "104.20.0.0/16",
    "104.21.0.0/17"
  ]
}
{
  "timestamp": "2022-09-19 12:14:33.457401266 +0530 IST",
  "input": "hackerone.com",
  "as_number": "AS13335",
  "as_name": "CLOUDFLARENET",
  "as_country": "US",
  "as_range": [
    "2606:4700:8390::/44"
  ]
}

CSV Output

asnmap also support csv format output which has all the information just like JSON output

echo hackerone.com | ./asnmap -csv -silent

Using with other PD projects

Output of asnmap can be directly piped into other projects in workflow accepting stdin as input, for example:

  • echo AS54115 | asnmap | tlsx
  • echo AS54115 | asnmap | dnsx -ptr
  • echo AS54115 | asnmap | naabu -p 443
  • echo AS54115 | asnmap | naabu -p 443 | httpx
  • echo AS54115 | asnmap | naabu -p 443 | httpx | nuclei -id tech-detect

Use asnmap as a library

Examples of using asnmap from Go code are provided in the examples folder.
