I want to use my Internet Service Provider's name in a script, and I don't know how can I do this.

Please help me, thanks in advance.


You can use many websites, that provided to to find your ISP name. One of them is whoismyisp.

And for get your ISP name, in bash script you can get this site by something like curl.

curl -s https://www.whoismyisp.org | grep -oP -m1 '(?<=isp">).*(?=</p)'

Also you can find ISP of any desired IPs with this command:

curl -s https://www.whoismyisp.org/ip/xxx.xxx.xxx.xxx | grep -oP -m1 '(?<=isp">).*(?=</p)'

Thats xxx.xxx.xxx.xxx is that IP you want to find its ISP.

Additional information: You can find your IP by bash with this command (thats may be helpful for scripts):

dig +short myip.opendns.com @resolver1.opendns.com

    @TaraSVolpe I'm glad I could help you – Ali Razmdideh Sep 22 '17 at 13:11

    This answer relies on the layout of this website, while ipinfo.io uses a well-defined JSON format. I don't understand why this answer is more upvoted. – NieDzejkob Sep 23 '17 at 15:16

    @NieDzejkob Maybe because ipinfo.io/org only give the AS number but not the name of the ISP – SebMa Mar 30 '18 at 17:31

    @SebMa When I ran Byte's answer on my machine in Ubuntu in Windows 10 (WSL) it returned the AS number plus the ISP name using curl ipinfo.io/org. None-the-less I up-voted both answers and the question because it's all good :) – WinEunuuchs2Unix Mar 30 '18 at 17:44
  • @NieDzejkob curl ipinfo.io/org does not output the full name of the AS but curl -s ipinfo.io/ASxxx | grep as-name does :) – SebMa Mar 30 '18 at 17:49

You could use e.g. the services of ipinfo.io to determine your public IP including some additional information like the provider company name.

The site can be normally visited in your browser, but if you query it from the command-line with e.g. curl, they respond in a clean and well-defined JSON format so that you don't need to parse any HTML:

$ curl ipinfo.io
  "ip": "xxx.xxx.xxx.xxx",
  "hostname": "xxxxxxxxxxxxxxxxxxxxxxxxxxx.xx",
  "city": "xxxxxxxx",
  "region": "xxxxxxxxxx",
  "country": "xx",
  "loc": "xxx.xxxx,xxx.xxxx",
  "org": "xxxxxxxxxxxx",
  "postal": "xxxxx"

To only show one value, you can directly send a request to the respective path. E.g. for the ISP name (org), try this:

curl ipinfo.io/org

Inspired by this answer.

    Yes, ipinfo is better than whoismyisp because of its JSON format +1 – Ali Razmdideh Mar 30 '18 at 17:55
  • @AliRazmdideh Very magnanimous indeed that you upvote the other guys answer :) – WinEunuuchs2Unix Aug 4 '19 at 18:40
  • @WinEunuuchs2Unix Thanks, I think it's better than mine. – Ali Razmdideh Aug 4 '19 at 19:15

First I fetch the Autonomous System number :

$ curl -s ipinfo.io/org
AS2094 Renater

Then I fetch the full name of that AS :

$ curl -s ipinfo.io/$(curl -s ipinfo.io/org | cut -d" " -f1) | awk '/as-name/{print$NF}'

$ whois $(curl -s ipinfo.io/org | cut -d" " -f1) | awk -F: 'BEGIN{IGNORECASE=1}/(as-?name|org-?name):/{sub("^  *","",$2);print$2}'

    For me it's not working. I just tested all answers in both Ubuntu in Windows 10 (WSL) and Ubuntu 16.04 with Kernel 4.14.27. Your option 1 above (Byte's answer) returns AS852 TELUS Communications Inc.. Your option 2 above returns nothing. The accepted answer uses curl -s https://www.whoismyisp.org | grep -oP '\bisp">\K[^<]+' and returns Telus Communications which is a limited version of Byte's answer but still good. This is one of those YMMV (Your Mileage May Vary) answers. – WinEunuuchs2Unix Mar 30 '18 at 18:02

    Apparently it depends on the provider or on what ipinfo.org has in their data collection. For me curl -s ipinfo.io/org gives AS3320 Deutsche Telekom AG while curl -s ipinfo.io/AS3320 | grep as-name gives DTAG (after a while). Also, the latter is again parsing HTML output (error-prone!). So I'll stick with ByteCommander's answer. – PerlDuck Mar 30 '18 at 18:03
  • @PerlDuck When I use Germany's AS3320 I get the same DTAG output you get. But I wonder if you use Canada's curl -s ipinfo.io/AS852 | grep as-name you get null output like me. – WinEunuuchs2Unix Mar 30 '18 at 18:07
  • @WinEunuuchs2Unix Yes, same for me. No output. I reckon curl -s ipinfo.io/org returns data based on the requesting IP while curl -s ipinfo.io/AS3320 returns data based on the given parameter (ignoring the request's IP). Anyway. Parsing HTML without a proper parser is almost always a bad idea. Do you know this famous answer on Stack Overflow? It's fun to read. – PerlDuck Mar 30 '18 at 18:23
  • @PerlDuck It is a fun read especially all the weird characters at the end. Throwing caution to the wind I did parse HTML code in bash: askubuntu.com/questions/900319/… – WinEunuuchs2Unix Mar 30 '18 at 18:40
