IP ranges by provider
Which network does an IP address belong to? These pages summarise the published and routed address ranges of major providers: how much address space each one operates, where it is located, which autonomous systems announce it, and how the addresses IPDebrief has analysed inside those ranges score for risk. Use them to recognise cloud and hosting traffic, verify genuine search engine crawlers, and allowlist CDN or relay egress addresses.

How provider matching works
An address is attributed to a provider when it falls inside one of that provider's ranges. Where ranges overlap, the most specific range wins, so a crawler or relay range is preferred over the broader cloud block that contains it. Range lists change as providers add, retire and transfer address space, so attributions are refreshed regularly. Belonging to a provider says what kind of network an address is on, not whether its traffic is legitimate; each address's own profile carries the risk evidence.
