What Is a Hotmail IP Address?


A Hotmail IP address is a registered Internet protocol identification assigned to messages originating from messages generated from that specific email provider. A list of registered Hotmail IP addresses exists to help verify legitimate messages and track potential threats.

An IP address is a unique number assigned to individual user accounts, devices and endpoints that access the Internet. These codes act as a fingerprint for each connection and allow each piece of hardware to connect to the Internet successfully. Hotmail IP addresses are used to ensure that each account is able to send and receive messages appropriately. This helps avoid accidental viewing of content by unwanted parties and limits malware and other kinds of attacks.
