If you want to change your IP address without using a VPN, you can disconnect your ISP modem for a few hours. In most cases, your ISP will assign you a new IP address when you connect to their network again. This is a quick and easy way to change your IP address without using a VPN.
Can you mask your IP address without VPN?
Yes. You can hide your IP address without using a VPN, by using Tor or a proxy server. However, there are downsides to both when compared to using a VPN. For example, browsing on Tor can be slow, and proxy servers don't encrypt traffic.
