Hi Valarmathi,
While Spectrum can discover and display the addresses for IPv4 only or IPv6 only devices, I don't believe there is an out of the box way to display BOTH IPv4 and IPv6 addresses for a dual stack device. However, you can customise the system to Display the IPv4 address in a newly created attribute while leaving the network address as IPv6.
So you would create a new attribute with the data type “internet address” and display the IPv4 address. Be advised though, If you have a huge number of devices with the same model type, then this newly created attribute gets created for all the devices and might impact the database.
So a possible solution is to create a new attribute to display the IPv4 address while the Network_Address (0x12d7f) attribute is used to display the IPv6 address.
