This topic lists the resources available for conducting research into indicators. To access the tools, in the Infoblox Portal go to **Security** > **Research** > **Resources**.

## <span style="color: #000000">Infoblox InfoRanks</span>

The Infoblox InfoRanks list ranks the top second-level domains by popularity. The list is updated regularly. For information, see *[Infoblox InfoRanks](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneThreatDefense/pages/35437577)*.

## <span style="color: #000000">Default TTLs</span>

The default TTL (time-to-live) list displays each threat class’s default TTL value in a threat feed. TTL values range from less than one day to a year, depending on the indicator’s type. For information about the TTL for threat indicators in a feed, see *[Default TTLs](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneThreatDefense/pages/35471706)*.

## <span style="color: #000000">Excluded Bogons</span>

A bogon is an internet address prefix that should never appear in a table for routing IP addresses. The Excluded Bogon page allows administrators to view invalid IP ranges that can be used by malicious entities. For information, see *[Excluded Bogons](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneThreatDefense/pages/35405977)*.

## <span style="color: #000000">Threat Classification Guide</span>

The guide defines (1) the common data-classification groups used in threat intelligence and (2) the properties of each group. For information, see *[Threat Classification Guide](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneThreatDefense/pages/35437517)*[.](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneThreatDefense/pages/35437517)

## Threat Insight Guide

The guide lists threat insight indicators along with a brief description for each indicator. For information, see *[Threat Insight Guide](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneThreatDefense/pages/203358417)*.

## Threat Actor Naming Conventions

Infoblox Threat Intel documents why and how threat actors are given names. For information, see *[Threat Actor Naming Conventions](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneThreatDefense/pages/610861663)*.
