Solid Dev Tools:AS Network Whois
About the AS Network WHOIS Lookup tool
Network packets (traffic) are transmitted over the Internet by traversing multiple networks run by different organisations - known as Autonomous Networks. Each of these organisations is assigned a number for their network, known as an ASN (Autonomous System Number.)
Each network peers with other networks, sharing the AS numbers of the networks they peer with.
You can perform a query known as "WHOIS" to identify which organisation operates a particular AS network.
Use Cases
Use the AS Network WHOIS tool on Solid Tools for Developers to:
- Identify which organisation is responsible for an ASN
- Find out contacts to report abuse or technical problems with an ASN
Usage
Enter an ASN in the "AS Number" field.
Optionally select a regional WHOIS server to send your query to.
Results
The raw output from the WHOIS database will be displayed.
The following example shows a WHOIS lookup for AS15418, the AS number allocated to Fasthosts - the data centre that hosts the server running Solid Tools for Developers.
