Thus, if someone has already requested a particular Dossier, the records shown could be up to a day old. You can also enter other identifiers, and Domain Dossier will act on the domains or IP addresses they contain:. Domain Dossier displays Whois records for the longest registered domain that contains the domain you entered or the domain associated with the IP address you entered.

For example, if you enter www. Domains often have two Whois records, one from the registry and a more detailed one from the registrar, and Domain Dossier will display both. It displays record text verbatim except that it removes bulky headers and footers when it can. The Whois records for an IP network provide information about its allocation or assignment such as:.

Domain Dossier displays a Whois record for the IP network allocation or assignment that includes the IP address you entered or the first IP address associated with the domain you entered. IP addresses can have multiple associated Whois records, but Domain Dossier only displays the most specific one.

As you see, you obtained the main IP address Other times, it will connect to whois. When it comes specifically to IP lookups in this case bgpview. Nowadays, network, domain and IP history are critical for investigating any infosec incident, offering the information needed to expose useful information such as where the domain was hosted, technical and personal details about the person involved, where the web servers were hosted, or what MX servers were used to send an email.

Primary internal IP addresses

You can do it by using our web-based interface, or by API. By using our API you can accomplish the same results. Our API supports a wide range of programming languages and integrations , but for this quick example we will launch a query against our database using the old terminal-based curl utility:.

A real-time map of the geographical IP address origin will be displayed as well.

The same applies to IP ranges—you can extract all the intel about any IP range in the world. The filter lets you order results by hostname, Alexa rank, computed company name, registrar, expiry date, creation date, mail and hosting provider. PTR records are not only useful for finding data correlation in your infosec research, but also to protect against spammers and malicious domain names that will try to exploit your mail server. Therefore, most popular email providers always check for PTR records by performing domain and IP lookups before accepting any incoming email from external hostnames.

In honor of that incident, the goal of this section is to determine IP ranges assigned to and used by Target Corporation. The primary purpose of DNS is to resolve domain names into IP addresses, so it is a logical place to start. Using the host command to query common DNS record types. Next I resolve the IP addresses for the hostnames above using host again and I try a few common subdomain names such as www. Starting with names like ns3. All of this leaves me with the following target. While a substantial hostname list can be generated in this manner, the mother lode of hostnames comes from a zone transfer.

Most DNS servers now reject zone transfer requests, but it is worth a try because many still allow it.

So far we have found seven Target nameservers: ns3. Unfortunately, all of those servers either refused the transfer or did not support the TCP DNS connections required for a zone transfer. A common mistake when gathering forward DNS results like these is assuming that all systems found under a domain name must be part of that organization's network and safe to scan. In fact, nothing prevents an organization from adding records pointing anywhere on the Internet.

This is commonly done to outsource services to third parties while keeping the source domain name for branding. For example, www.

Is this part of Target's network, or is it managed by a third party we might not want to scan? Three quick and easy tests are DNS reverse-resolution, traceroute, and whois against the relevant IP address registry. The first two steps can be done by Nmap, while the Linux whois command works well for the third.

These tests against target. The Amazon. If we were hired by Target to test their security, we would need separate permission from Amazon to touch this address space. Web databases can also be used to find hostnames under a given domain. Their handy table shows the netblock owner too, which catches cases such as Amazon running www. We already knew about some of the discovered hosts, but we would have been unlikely to guess names such as sendasmoochie. Google can also be used for this purpose with queries such as site:target.
