DNS sweeping backwards?

[caffix]

Many factors can influence the order of the requests, and more than one sweep can be taking place at once. Also, the sweep takes place on IP addresses with lower and higher host numbers than the IP originally discovered.

If you would like to develop a new algorithm for the reverse DNS sweeping, I would welcome and appreciate your contribution to the project!

I think I've phrased my question poorly. Look at line 385 in datamgmtsrv.go

ptr = utils.ReverseIP(ip.String()) + ".in-addr.arpa"

// AttemptSweep - Initiates a sweep of a subset of the addresses within the CIDR`

Don't you want to perform this sweep on the current CIDR subset, not the reverse?

The DNS request for the PTR record associated with IPv4 address 204.48.17.202 uses the following name: 202.17.48.204.in-addr.arpa

Please see the following Wikipedia page for further details: https://en.wikipedia.org/wiki/Reverse_DNS_lookup

Thank you for the reply and sorry for the wasted time - my misunderstanding.

No worries! Perhaps you would like to contribute to the project, since there are many other things to learn in the process. The link to the Discord server in on the README page, where we can discuss it further. Thanks!
