127.0.0.3



Here you can find all lookup results for loopback IP address 127.0.0.3 which is located in 127.0.0.0/8, a reserved range for loopback addresses to the local host (RFC 6890).



IP address 127.0.0.3 is registered as a loopback interface address which is also known as localhost or local host. In computer networking, localhost is a hostname that means this computer. It is used to access the network services that are running on the host via its loopback network interface. Using the loopback interface bypasses any local network interface hardware.
This type of address is also used as a means to validate that a locally connected physical networking card is working as expected and the TCP/IP stack is installed.

The local loopback mechanism is useful for testing software during development, independently of any networking configurations. For example, if a computer has been configured to provide a website, directing a locally running web browser to http://localhost or http://127.0.0.1 may display its home page.

Whois lookup

Do you want to know who is operating this IP? Consulting the whois data is your best bet, as it gives out the official ownership information. WHOIS is an international recognized protocol to query worldwide databases that store information on internet resources. It was documented in RFC 3912 by the Internet Society back in 2004, but is still current. It has been reported that the protocol will soon be obsolete, due to privacy reasons, and will be replaced with a less transparent system.
