AS15169 is an Autonomous System Number, not an IP address. One Autonomous System can originate many IP prefixes under a common routing policy, so ASN data gives broader network context than looking at one address alone.
What is an ASN?
An Autonomous System Number identifies a network or collection of networks that presents a common routing policy to the global internet. ISPs, mobile carriers, cloud platforms, content-delivery networks, universities and large enterprises can operate one or more Autonomous Systems.
What does an ASN lookup tell you?
RDAP registration for an ASN can identify the registered handle and name, country field, number range, events and related entities. Combined with IP data, the ASN helps explain which broader network announces or carries the address you are investigating.
Why ASN data matters for IP analysis
City-level geolocation may be uncertain, but the ASN can still provide strong network context. For example, it can indicate that an address belongs to a large consumer ISP, a hosting provider, a cloud network or a content platform. This can help interpret server logs, routing issues and security signals.
ASN versus ISP or brand name
An ASN's registered organization, a consumer-facing ISP brand and a parent company do not always use the same name. Companies can also operate several ASNs for different regions or business units. Treat the registration as network-resource information rather than a simple company directory.
ASN and BGP
Autonomous Systems exchange routing information through the Border Gateway Protocol. An ASN is therefore closely connected with how IP prefixes are announced across the internet. This lookup does not attempt to reproduce a full live BGP routing table; it focuses on registration context and links into curated major-network pages.
Curated network pages
IP-Lookup.com maintains a limited set of crawlable profiles for major networks. Those pages retrieve current RDAP information when possible rather than freezing volatile routing ranges into permanent static text. Arbitrary ASN searches remain tool results instead of creating unlimited thin indexable pages.
