iSCSI: TargetAddress format

["Lakshmi Ramasubramanian" <nramas@windows.microsoft.com>]

Title: Message

The format of TargetAddress (Section 11.8) is given as

 

 TargetAddress=domainname[:port][,portal-group-tag]

 

In the examples given

 

 TargetAddress=[1080:0:0:0:8:800:200C:417A],65

 TargetAddress=[1080::8:800:200C:417A]:5003,1

 

What does the value within brackets indicate? Is it

an IPv6 address?

 

thanks!
