Neutral Activity
There is no recent abuse activity, or the IP address is whitelisted.
Whitelisted Subnet
Whitelisted netblocks are typically owned by trusted entities, such as Google or Microsoft who
may use them for search engine spiders. However, these same entities sometimes also provide cloud
servers and mail services which are easily abused. Pay special attention when trusting or
distrusting these IPs.
IPv6 SLAAC Note
Public IPv6 addresses may implement the SLAAC
privacy extension. With SLAAC, the interface identifier is randomly generated. SLAAC also implements a
configurable time out, so that the original IPv6 interface addresses will be discarded in favor of a new
interface identifier.
