IP addresses

IP addresses identify the devices in your networks. From the IP addresses page, view details about the IPv4 and IPv6 addresses we found for your organization.

info

We only show IP addresses with at least one open port or FDNS domain. For a complete list of all the networks we identified for your organization, navigate to the Networks page.

IP addresses table

The IP addresses table includes the IP addresses we found in your networks. It also lists details such as the corresponding domain names from reverse DNS lookups, how many services and ports are active, and how many instances of vulnerabilities we found for each.

Use the information to evaluate details for specific IP addresses in your network, such as before you take actions to reduce large numbers of vulnerabilities.

For information about table options, see Tables.

Columns and filters

• To add or remove information in the table, select Columns and choose the columns to view.

• To view and manage IP addresses that meet specific criteria, such as those with more than one open port, select Filters and then select how to narrow the data.

Name	Description
IP address	Active IPv4 or IPv6 address found in your networks.
Domain	Filter for finding IP addresses whose domain names resolve through forward DNS (FDNS) but have no corresponding reverse DNS (RDNS) records.
RDNS	Domain name for the IP address identified from a reverse DNS (RDNS) lookup. RDNS uses an IP address to identify a domain name.
FDNS count	Number of domain names for the IP address identified from a forward DNS (FDNS) lookup. FDNS uses a domain name to identify an IP address.
Port count	Number of open ports identified for the IP address, including ports in the system, registered, and private ranges.
Service count	Number of service, product, and version combinations on open ports. If there are multiple instances of a combination running on multiple ports, we only count the combination once. For example, if there are two instances of http, Apache httpd, 2.0.0, we only count the combination once.
Vulnerability instance count	Number of vulnerability instances found for the IP address. An instance is a vulnerability with a CVE number related to a service, product, and version combination on an open port. If there are multiple instances of a combination running on multiple ports, we count the vulnerabilities for each port as an instance. For details, see Vulnerability instances.
IP address tags	Reasons the IP address is potentially vulnerable. For details, see Tags.
Network count	Number of networks the IP address belongs to.
FDNS	Filter for finding IP addresses based on their FDNS domain names.

Find IP addresses for a domain name

To view the IP addresses identified for a domain name through FDNS lookup, filter the IP addresses table.

1. From the IP addresses page, select Filter in the IP addresses table.

2. Under Columns, select FDNS.

3. Under Operator, select equals.

4. Under Value, enter the domain name.

   

   The table automatically filters the results to show the IP addresses.
