Network Discovery Algorithm
http://apple1.sub.domain.com/~chema/dir/fil.doc
http -> Web server
GET Banner HTTP
domain.com is a domain
Search NS, MX, SPF records for domain.com
sub.domain.com is a subdomain
Search NS, MX, SPF records for sub.domain.com
Try all the non verified servers on all new domains
server01.domain.com
server01.sub.domain.com
Apple1.sub.domain.com is a hostname
Try DNS Prediction (apple1) on all domains
Try Google Sets(apple1) on all domains

11) Resolve IP Address
12) Get HTTP Banner of http://IP
13) Use Bing Ip:IP to find all domains sharing it
14) Repeat for every new domain
15) Connect to the internal NS (1 or all)
16) Perform a PTR Scan searching for internal servers
17) For every new IP discovered try Bing IP recursively
18) ~chema -> chema is probably a user

19) / , /~chema/ and /~chema/dir/ are paths
20) Try directory listing in all the paths
21) Search for PUT, DELETE, TRACE methods in every path
22) Fingerprint software from 404 error messages
23) Fingerprint software from application error messages
24) Try common names on all domains (dictionary)
25) Try Zone Transfer on all NS
26) Search for any URL indexed by web engines related to the hostname
27) Download the file
28) Extract the metadata, hidden info and lost data
29) Sort all this information and present it nicely
30) For every new IP/URL start over again
