Hi Team,
Is it possible to search for an IPv6 IP-range from xxxx to zzzz?
Currently, we can just search for IPv4 ranges.
Many thanks in advance.

Absolutely! IPv6 scanning has been supported in the Network Scanner for a long time. There are two ways of doing it:
IPv6 address range
The Network Scanner runs from the lowest to the highest IP address. Due to a very large pool of possible addresses, only up to four last octets can vary. In practice, probably only the last two, for example 2001:db8::1 to 2001:db8::ffff. This can be useful when the IP addresses are allocated by a DHCP server within a known range. This mode can be used by entering an IP address range manually.
IPv6 neighbour discovery
The Network Scanner sends out a multicast ping to ff02::1 and awaits replies. After that, it runs through a list of addresses that responded. This may be handy for discovering auto-configured IPv6 devices. This mode can be used by selecting one of the local addresses in Options - IP Address - Detect Local IP Range.
