In Individual Discovery a single IP address is specified and the discovery of that network element is carried out. Reconciliation module contains two types of discrepancies which are depending upon the types of Discovery carried out as Range Based and Device Based. Discrepancies are nothing but the differences found by comparing the master database and discovered database.
