TODO Introduction¶
PLAT: As defined in [RFC6877], PLAT is provider-side translator (XLAT) that complies with [RFC6146]. It translates N:1 global IPv6 addresses to global IPv4 addresses, and vice versa.¶
CLAT: As defined in [RFC6877], CLAT is customer-side translator (XLAT) that complies with [RFC6145]. It algorithmically translates 1:1 private IPv4 addresses to global IPv6 addresses, and vice versa. The CLAT function is applicable to a router or an end-node such as a mobile phone. The CLAT should perform IP routing and forwarding to facilitate packets forwarding through the stateless translation even if it is an end-node. The CLAT as a common home router or wireless Third Generation Partnership Project (3GPP) router is expected to perform gateway functions such as being a DHCP server and DNS proxy for local clients. The CLAT uses different IPv6 prefixes for CLAT-side and PLAT-side IPv4 addresses and therefore does not comply with the sentence "Both IPv4-translatable IPv6 addresses and IPv4-converted IPv6 addresses SHOULD use the same prefix." in Section 3.3 of [RFC6052]. The CLAT does not facilitate communications between a local IPv4-only node and an IPv6- only node on the Internet.¶
