Issue setting RemoteAddresses of a FirewallRule with a range of IPv6 addresses

[nmehtaMS]

For the following code

rule.RemoteAddresses = remoteAddresses;

when assigning an array of remoteAddresses which includes an IPv6 address range eg
1234:1030:20e:3::6f/127
start IP 1234:1030:20e:3::6e
last IP 1234:1030:20e:3::6f

it fails to set the remoteAddresses property and throws an exception

Exception Stack Trace

This works fine when the IPv6 CIDR is /128 eg 1234:1030:20e:3::6f/128
