IP Address Ranges
There are no known IP addresses belonging to this network
We don't currently have any network speed data for this network.
There are no domains currently hosted on this ASN.
There are no peers for this ASN.
Autonomous System Numbers (ASNs) are assigned to entities such as Internet Service Providers and other large organizations that control blocks of IP addresses. This network page, and the organization field that's shown on the main IP address information page and also returned in the geolocation API are based on the ASN.
The ASN details will often correspond to the IP address owner, but for smaller organizations it may be that organization's parent, or their ISP.
