There are some websites like ipinfo.io that give clients some information for an IP address like location, ASN and etc. How can I obtain mentioned information without third party tools in Linux?

  • The answers for [that question](https://superuser.com/questions/1065263/how-to-get-a-computers-internet-ip-address-location-using-command-line) are using third party tools – Alireza Alipour Oct 30 '19 at 20:20
  • Curl is a third party tool? – harrymc Oct 30 '19 at 20:23
  • `curl` is not a third party tool, but [ipinfo.io](https://ipinfo.io) is a third party tool. – Alireza Alipour Oct 30 '19 at 20:27
  • There is no way that you can download locally the entire database used by `ipinfo.io`, or if you do then to use it. You need an external repository. – harrymc Oct 30 '19 at 20:32
  • Unless you construct a local DB of all locations of all IP addresses (and maintain it...) you'll have to use 3rd party servers for this. For the purely network information, `whois` and `dig` will help. – xenoid Oct 30 '19 at 20:49
  • Thank @xenoid very much, using `whois` is the answer that I was looking for it, if you can answer this question by yourself to make this question an answered question. – Alireza Alipour Oct 30 '19 at 21:06
