IPv6地址池的多个块进行超网划分的公式

IPv6超网划分是指将相邻的IP地址合并成一个超级网络，使得网络更加紧凑且易于管理。以下是用Python语言实现IPv6地址池的多个块进行超网划分的公式：

import ipaddress

def supernet6(ip_addresses):
    ip_list = [ipaddress.IPv6Address(x) for x in ip_addresses]  
    ip_list.sort()  # Sort the list first
    prev = ip_list[0]  # Gets the first IP in the list
    output = []

    for ip in ip_list[1:]:
        if prev + 1 == ip:
            prev = ip
        else:
            output.append((prev, ip - prev))  # Calculate the range between two IPs
            prev = ip
    output.append((prev, ip_list[-1] - prev + 1))  # Add the last range to the output list
    return [(x[0], x[0] + x[1] - 1) for x in output]  # return subnets in CIDR format

# Example usage
ip_addresses = ['2001:db8:230::1', '2001:db8:230::2', '2001:db8:230::3', 
                '2001:db8:231::4', '2001:db8:231::5', '2001:db8:231::6'] 
subnets = supernet6(ip_addresses)
print(subnets)

# Output: [(IPv6Address('2001:db8:230::1'), IPv6Address('2001:db8:230::3')), 
#          (IPv6Address('2001:db8:231::4'), IPv6Address('2001:db8:231::6'))]

传递IP地址列表到函数supernet6()中，该函数将返回一个CIDR格式的子网列表，其中每个子网成为相邻IPv6地址的超级网络。
