Week 8 Posting - IPv6 vs IPv4 IPsec

 

IPv6 has now been around for a while. It helped us alleviate the problem of running out of IP addresses. It did this by creating 340 trillion possible unique IP addresses by using a 128-bit addressing scheme. Is IPv6 more secure than IPv4 though?

Initially most people believe the IPv6 is more secure as it is new and has built in encryption and capabilities of checking data packets for integrity. IPv4 is capable of using IPsec but is used mostly for VPNs and not end-to-end security like IPv6. Ultimately, it boils down to how the IPsec is being used whether or not it is more secure.
