我知道ipv4地址是32位。但是有可能将ipv4地址从32位更改为64位吗？
答案 0 :(得分：0)
该功能称为enhanced-ipv4或EnIP，请查看此文档（具有64位地址空间的IPv4 2015年1月）：
Enhanced IP (EnIP) was designed to minimize impact on core and border routers. ... EnIP packets carry additional address bits and state in an IP option, eliminating routing table updates like IPv6. EnIP supports end-to- end connectivity, a shortcoming of NAT, making it easier to implement mobile networks. Host renumbering is also not required in EnIP as has been the case with other 64-bit protocol proposals

增强型IP（EnIP）是一种将IP地址空间从32位扩展到64位的方法。 64位地址看起来像连接在一起的两个IP地址。增强型IP比IPv6更容易实现。为了说明，有432个IPv6 RFC和1个增强型IP RFC。
Examples addresses for comparison:
IPv6 address: 2001:0101:c000:0202:0a01:0102::0
EnIP address: 192.0.2.2.10.1.1.2
IPv4 address: 192.0.2.2
