Frequently Asked Questions
Can I use IPv6 on my device now?
Most modern equipment and operating systems already have IPv6 capability turned on or available to activate. Enabling it on your home router and devices will allow you to utilize IPv6 alongside IPv4 access.
Is IPv6 more secure than IPv4?
Yes, IPv6 builds in native encryption for end-to-end security, protecting communication from attacks that exploit IPv4’s vulnerabilities. Its huge address space also offers greater resilience to reconnaissance and spreading malware.
Will IPv4 ever be completely phased out?
Eventually yes, but likely not for decades. The legacy install base of IPv4 means it will co-exist with IPv6 through dual-stacking during a long migration phase before being gradually retired.
What are the challenges of migrating to IPv6 for businesses?
Upfront infrastructure upgrades, compatibility limitations, staff retraining costs, and the complexity of managing both protocols in tandem during transition. These hurdles contribute to hesitancy in adopting IPv6.
Which ipv6 prefix is reserved for communication?
The 2000::/3 address block is designated for Global Unicast addresses used for generalized public routing and communication.
How many ipv6 addresses are available?
340 undecillion (340 followed by 36 zeros)! This is over 6×10^23 times more addresses than IPv4 provides.
Why ipv6 was used to replace ipv4?
The internet’s exponential growth demanded a new version protocol with vastly larger addressing capabilities and built-in security to sustain expanding networks of people, devices, and usage into the future that the limited IPv4 could not deliver.
