What do the different return codes in the XBL mean?
The DNS return code (127.0.0.?) denotes the source of the data in the XBL or the SBL-XBL and ZEN combined zones. Only one code is currently used by XBL:
127.0.0.4 – XBL
127.0.0.5 and 127.0.0.6 are no longer in use at this time. 127.0.0.5, 127.0.0.6 and 127.0.0.7 remain allocated to XBL for possible future use.
