IPv6 Adoption: What It Means for Your IP Address article illustration

IPv6 exists because IPv4 does not have enough unique addresses for the modern internet. Many networks now run both systems at the same time, which is called dual-stack networking.

If your connection supports IPv6, you may see a longer address made from letters, numbers, and colons. If it does not, you will usually see only an IPv4 address.

Why IPv6 matters

IPv6 gives networks vastly more address space and can simplify some routing and configuration tasks. For most everyday users, the practical change is simple: some websites and apps may connect over IPv6 while others still use IPv4.

Should you disable IPv6?

Usually, no. Disabling IPv6 can cause connection problems and does not improve privacy by itself. If you use a VPN, check that it either supports IPv6 properly or blocks IPv6 leaks.
