¿µ¹®³»¿ë¿ä¾à | DS-Lite [RFC6333] is a transition technique that enables operators to multiplex public IPv4 addresses while provisioning only IPv6 to users. DS-Lite is designed to continue offering IPv4 services while operators upgrade their networks incrementally to IPv6. DS-Lite combines IPv4-in-IPv6 softwire [RFC2473] and Network Address Translator IPv4/IPv4 (NAT44) [RFC3022] to enable more than one user to share a public IPv4 address. While Appendix A of [RFC6333] explains how to deploy DS-Lite within specific scenarios, the standard is to describe problems that arise when deploying DS-Lite and what guidance should be taken to mitigate those issues. | ||
