I‘m getting lots of spam from few IPs. How do I find the owner of an IP address and report them to concern parties?
All public IP address on the Internet is registered to ISP or an owner or a larger organization. Each IP address is recorded in the whois database. You can query this database to get owner name, phone, email address and so on the Internet using whois command line client.
Find IP Address For A Host Name
For instance to find the IP address for a www.cyberciti.biz open a command line and type in:
