ASN summary
How to read the scale of AS1101
IP-EEND-AS - SURF B.V. currently shows 19 prefixes and 44 upstream, downstream, or peer relationships. Larger prefix inventories often indicate broader network footprint, but they should still be read together with country and peering context.
When is an ASN page most useful?
ASN landing pages are more useful than a single IP page when you want cloud provider attribution, routing research, infrastructure comparison, or network topology analysis at the organization level.
How should you read the country, organization, and role of AS1101?
IP-EEND-AS - SURF B.V. is currently associated with an unknown region. Country data is only a starting point; the more important signals are the organization name, website, prefix volume, and peering relationships that reveal whether the network behaves like a cloud platform, ISP, CDN, or enterprise backbone.
What should you inspect next after the AS1101 page?
This page is currently showing live ASN data that can be used for peer, prefix, and network scale analysis. The most useful next step is usually to return to a related IP landing page, then compare that concrete address with this ASN profile and with broader topic pages for routing, cloud attribution, or WHOIS ownership analysis.

Frequently asked questions about this ASN page
What does AS1101 represent?
AS1101 is an autonomous system number used to identify an independently operated network. The current page associates it with IP-EEND-AS - SURF B.V. in an unknown region, which helps determine whether it behaves like a cloud provider, ISP, CDN, or enterprise backbone.
What are peers, upstreams, and prefixes useful for on the AS1101 page?
They help explain the scale, interconnection depth, and route structure of AS1101. Richer peering and upstream data often indicate broader network reach, but they should still be interpreted together with prefixes and related IP landing pages.
What should you do after reviewing AS1101?
The best next step is usually to return to a concrete IP landing page to see how a specific address maps into AS1101, then continue into cloud, WHOIS, or routing topic pages to understand the network in a broader context.
