How to Set up Multiple IP Addresses on a Computer [https://www.loadtestingtool.com/help/how-setup-ip.shtml]

ok but I don't want to have more than one

<div>
One of the addresses is the APIPA address (Automatic Private IP Address) that the computer gives itself when it can't reach a DHCP server or have a static address.<br />
<br />
What does IPCONFIG show when you run that in a command prompt?

You can always disable the APIPA address, but you would then have to specify an alternative. Has someone manually configured an APIPA address in the Alternate Configuration tab?

hi experts,

two ipv4 addresses?

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.

TCP/IP

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
