What is cons of disabling IPv6

Microsoft also warns against disabling IPv6. You may remove your acute problem, but you're letting yourself in for much bigger problems further down the line. The reason being that IPv6 is integral to the Windows operating system. Consequently, applications are not tested in situations where IPv6 is disabled.

What happens if I disable IPv6 on my router

Some people connecting to dual-stacked sites notice connection delays that will disappear once IPv6 is disabled. This can only happen if the IPv6 path has some kind of problem which causes the IPv6 connection to time out before falling back to IPv4. Sometimes, connections fail completely until IPv6 is disabled.

Is enabling IPv6 a security risk

Security issues associated with an IPv6 implementation will generally surface in networks that are new to IPv6, or in early phases of the IPv6 transition. These networks lack maturity in IPv6 configurations and network security tools.

Does disabling IPv6 increase speed

No, it won't, at least not in any noticeable way. IPv6 processing was initially a bit slower because it was a new technology, and it uses more memory, but over time the difference got smaller and I don't think that will ever become a real issue. As an end-user you will not experience any slowdown.

Is there any benefit to enabling IPv6

Key benefits to IPv6 include: No more NAT (Network Address Translation) Auto-configuration. No more private address collisions.

Should IPv6 be enabled or disabled on router

Likewise, disabling IPv6 can cause certain problems, especially if your router is already using an IPv6 address. However, you should keep IPv6 enabled even if you use an IPv4 network or install a VPN that supports IPv6, like NordVPN. Otherwise, some Windows features (like Quick Assist) might not work properly.

Does IPv6 make WIFI faster

In general, there's no major difference between IPv4 vs IPv6 speeds, though some evidence does suggest that IPv6 might be slightly faster in some situations.

What can someone do with your IPv6

Your IP address is essential for sending and receiving information online. But if a hacker knows your IP address, they can use it to seize valuable information about you. Using it as a starting point in a broader attack, they could hack your device or intercept your online traffic, just for starters.

Is it better to have IPv6 on or off

Turning on IPv6 has no noticeable speed differences yet. You get added redundancy. For example if you turn off IPv4 or fumble the DHCP setting for your IPv4 network for whatever reason, sites that offer IPv6 will still work. A lot of major sites have both IPv4 and IPv6 working.
