Some applications are deployed across network blocks. Only networks that are dedicated to an application are provided.
ISC Network
Some organizations deploy all or parts of an application solution through their own infrastructure instead of third party hosting providers like AWS or Google Cloud Platform. The following is a sample of active IP addresses on the ISC Network.
ASN Description | ASN | Route | Location | IP | Shared |
---|---|---|---|---|---|
ISC F-Root Ams1 | AS30132 | 2001:500:60::/48 | Netherlands | 2001:500:60:d::52 | |

Other Networks
There are tens of thousands of Internet network providers and we make an effort to track as many as we can, but we have less coverage for niche and local providers. The following is a sample of ISC IP addresses on this type of network.
ASN Description | ASN | Route | Location | IP | Shared |
---|---|---|---|---|---|
Deft.Com | AS23352 | 2001:1838:2000::/46 | United States | 2001:1838:2000:41b::123:2000 | |
Deft.Com | AS23352 | 204.93.204.0/22 | United States | 204.93.207.11 |
Hosting
Cloud hosting vendors like AWS and Microsoft Azure provide cloud-based computing and network resources to deliver applications. The hosting platforms used by ISC are summarized below by geographical points-of-presence (PoP). Each PoP can host many IPs to deliver an application.

Content Delivery Networks - CDNs
In order to get information to end users more quickly, many applications are distributed from multiple geographical points-of-presence (PoPs) using Content Delivery Networks (CDNs). Each PoP can host many IPs to deliver an application. A sample IP is provided.
Take special note of CDNs that use Anycast technology. Anycast makes it possible to route a single IP address to a variety of different geographic locations. In other words, one global Anycast IP is hosted in multiple geographic locations.
