A plain-language explanation of hardware VPNs, how they differ from the VPN app on your phone, and where a home-IP router kit like FlashedRouter fits into the category.
A software VPN is an app: you install it on a phone, laptop, or tablet, tap connect, and that one device's traffic routes through an encrypted tunnel to a server somewhere. A hardware VPN does the same encrypting-and-tunneling job, but at the router level — every device that connects to that router gets tunneled automatically, with nothing to install.
Software VPN apps are quick to try and easy to toggle per device, which is exactly right for occasionally masking one device's location — watching a show unavailable in your region, for instance. They're less convenient when you want every device in a household or a travel bag covered without re-installing and re-configuring an app on each one, and most consumer VPN apps aren't designed to make a device convincingly look like it's on a specific home network rather than just "some VPN server."
Hardware VPNs solve the household/consistency problem directly: set it up once at the router, and every phone, laptop, and smart-TV behind it inherits the same tunnel without further setup.
Within hardware VPNs, there's a narrower product category built specifically around keeping your home IP address while traveling — sometimes called a home-IP kit. These ship as a matched pair: one router stays plugged in at home, a second, smaller router travels with you. The travel unit tunnels back through the home unit, so any service you connect to sees your home network's address, not the country or city you're actually in. FlashedRouter and a handful of other vendors, including keepyourhomeip.com, work this way.
A third, related category is the mesh VPN — software like Tailscale that connects your own devices to each other in a private network. It solves a different problem again: reaching a specific device (a home server, a NAS) rather than making your general browsing look like it's coming from home. See our full FlashedRouter vs. Tailscale comparison for the details.
