Mobile IPv6 aims to support mobility in IPv6 networks by allowing devices to maintain ongoing connections while moving between different networks. It operates in two modes: basic operation uses bidirectional tunneling between the mobile node and home agent, while route optimization establishes routes directly between the mobile node and correspondent nodes. Route optimization improves performance but introduces security challenges in authenticating binding updates. Evaluations found Mobile IPv6 reduces problems from triangular routing and ingress filtering compared to Mobile IPv4, but securing neighbor discovery and authorizing binding updates remain vulnerabilities.

38. Final Words – Mobile Ipv6

39. “ Communications should be much faster,&quot; Deering says. &quot;We also thought it was going to be more secure. But now it doesn't look like it's going to be more secure.&quot;

40. “ Backers of IPv6 have suffered another setback, as security experts punched holes in their planned strategy for supporting mobile IPv6 communications.”
