IPv6/IPv4 Coexistence - other options
Network Address Translation (NAT)
- Manipulates Addresses
- Blocks use of IPv4 / IPv6 End-to-End Security
- Breaks current Mobile-IP Mechanism
Application Layer Gateways (ALG)
- Requires knowledge of applications which use addresses
- New Applications may require ALG changes
- Unpredictable Application Failure
Protocol Translators
- Complex : but under consideration
- Stateless Translation being worked on now
No-NAT
- A new Suggestion
- Dynamically assigned temporary addresses
