We enumerated the SRV (Service) records. We know that they are using a jabber (XMPP).
We also obtained the IP and the ports that these services are running.
Command: dnsrecon -t srv -d domain

3. Zone Transfer:
The security problem with DNS zone transfer is that it can be used to decipher the topology of a company’s network.
Specifically when a user is trying to perform a zone transfer it sends a DNS query to list all DNS information like name servers, host names,MX and CNAME records, zone serial number, Time to Live records etc.Due to the amount of information that can be obtained DNS zone transfer cannot be easily found.
Command: dnsrecon -t axfr -d domain

4.Top Level Enumeration:
It shows top level domain name with their Ip address.
Command: dnsrecon -t tld -d domain

5.Saving Enumeration Result:
To save all enumeration result we would you following command.
