Hi,
I recently started supporting an application.
We often get IP address in error logs something like: Couldn't connect to 1.2.3.4, Time Out. We've many systems (servers) in whole application infrastructure.
There is no document which says that this ip belongs to this server, probably because ips are not static or servers are being referred by their names to no one cared for ips.
Is there anyway to determine hostname from ip address?
I checked some websites but our ips are "unknown" to them, may be some firewall thing.
Any help would be appreciated.
Thanks.
