Indeed, his blog was the most documented resource I could come across on the topic.

Thanks Henrico for an interesting question about undocumented DBCC commands.
Clear explanation I found in this blog from Paul White. Interesting is also this Paul Randal's blog.😉

With the introduction of sys.dm_db_database_page_allocations in SQL Server 2012 we probably shouldn't be using DBCC IND any more - not because sys.dm_db_database_page_allocations is any less unofficial than DBCC IND (both are totally unofficial as far as I know) but because it (a) provides more information that DBCC IND and (b) gives us the information in the form of a nice system view which we can select from and join with other tables and so on without having to create a temporary table to hold the information.

I went by Gail's opinion and as usual, she was right.

I wouldn't say that it is unofficial. DBCC IND was undocumented but is now on the deprecation list. For that reason and the nice easy friendly format that comes from the sys.dm_db_database_page_allocations function, I would recommend using the function instead (despite it also being undocumented).
