Explanation:
Wikipedia iSCSI Addressing
Special names refer to both iSCSI initiators and targets. iSCSI provides three name-formats:

l iSCSI Qualified Name (IQN) – Format: iqn.yyyy-mm.{reversed domain name} (e.g. iqn.2001- 04.com.acme:storage.tape.sys1.xyz) (Note: there is an optional colon with arbitrary text afterwards. This text is there to help better organize or label resources.), [A above] l Extended Unique Identifier (EUI) – Format: eui.{EUI-64 bit address} (e.g. eui.02004567A425678D)
l T11 Network Address Authority (NAA) – Format: naa.{NAA 64 or 128 bit identifier} (e.g. naa.52004567BA64678D)
