Internal database snapshot

    I ran dbcc checkdb on databases and noticed the following message:

    Internal database snapshot has split point LSN = 00000012a:00000222:0001 and first LSN = 00000012a:00000221:0001.

    what does this signify?

    CheckDB creates a hidden snapshot to run against, to allow it to have a transactionally consistent view of the database. That's just the LSN that the database was at when the snapshot was created.
