custom ipv6 subnet allocation empty value

[sorudev]

when prompted about custom nested ipv6 subnet you can hit enter without providing one. It should either prompt you thats incorrect value and repeat question or disable ipv6 but its not doing it. Currently installator just goes to next step which leads to an error later on while minting lease tokens:

Do you want to allocate the entire address range of the subnet 2001:ZZZZ:XXXX:4468:9000::/72 to Evernode? [Y/n] n

Please specify the nested IPv6 subnet you want to allocate for Evernode (this must be a nested subnet within 2001:ZZZZ:XXXX:4468:9000::/72 subnet): 
main: line 641: [: Params not specified.: integer expression expected
Using Params not specified. IPv6 subnet on ens18 for contract instances.
