First I doubt that this dataset is even sufficient to describe all possible attacks at the IPv4 level. This dataset is from 1999 and in the mean time TCP was developed further (for example TCP fast open) or new attacks were discovered (like TCP split handshake).
Apart from that IPv6 is not just not an extension of the address range. The header format is different and it provides different mechanisms for extensions which could be misused in attacks. Also ICMP and ICMPv6 have some significant differences etc.
please specify any attack that won't be detected using the above features.
This would be too broad. But a simple search will you provide with a wealth of information, for example IPv6- IPv4 Threat Comparison v1.0 where within "Attacks with New Considerations" it also shows attacks new with IPv6.
