有人可以帮助我计算IPv6地址的十进制值吗？
我需要将公式放在VBA中以制作自定义excel公式。我知道IPv4的公式，我已经读过它类似但我似乎无法弄明白。我需要这样才能将IPv6地址映射到ip2location CSV。

我有一些你应该可以开始使用的Excel IP功能。
=SubnetIPv4(IPv4,Bits,Offset) =IsIPv4(IPv4)
IP Address Bits Offset Result Result
10.11.12.13 26 0 10.11.12.0 TRUE
Notes:
Macros must be enabled
IPv4 is a string representing an IPv4 address in dotted decimal format
Bits is an integer (0 to 32) representing the number of mask bits
Offset is an integer representing the host address offset into the subnet
Using Offset 0 will retun a subnet for any IP address
Using IPv4 of 255.255.255.255 and Offset 0 will retun a mask of Bits size
=SubnetIPv6(IPv6,Bits,Offset) =IsIPv6(IPv6)
IP Address Bits Offset Result Result
fe80::1dce:e8b3:1a14:2c3b 10 :: FE80:0:0:0:0:0:0:0 TRUE
Notes:
Macros must be enabled
IPv6 is a string representing an IPv6 address in standard format (leading 0s are optional and :: works)
Bits is an integer (0 to 128) representing the number of mask bits
Offset is a string representing the host address offset into the subnet in standard format (leading 0s are optional and :: works)
Using Offset equivalent to 0 (::, ::0, 0:0:0:0:0:0:0:0, etc.) will retun a subnet for any IP address
Using IPv6 of FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF and Offset equivalent to 0 will retun a mask of Bits size

IPv6地址的十进制值会很大。您需要128位无符号整数，但VBA中没有此类数据类型。 因此，据我所知，您无法将IPv6地址作为整数进行操作。
