Live PTR

First of all, an important notice has to be done about names (or "descriptions") of IP addresses. If you know about the real objects, to which addresses belong, it is recommended to create those objects and then allocate IP addresses to them. This approach will keep your dataset consistent and cross-linked. Address descriptions normally should contain supplementary, but useful information: the role or a well-known DNS name of a particular address.

The feature allows matching description of each IP address of the current IP subnet with DNS PTR record, resolved online. RackTables highlights each address accordingly to its current description and DNS data; however, it is a rough estimation if each particular description is correct or not. It is left up to the user to decide, if DNS data, as more accurate, should be imported into DB.
