ASN summary
How to read the scale of AS35228
O2BROADBAND Telefonica UK Limited currently reports 132 prefixes and 44 upstream, downstream, or peer relationships. These counts describe the current dataset; they do not by themselves prove network quality, reach, or service use.
What can an ASN page answer?
An ASN page shows the public organization label, country or region, BGP prefixes, and available peer and upstream relationships. It adds network context but cannot confirm a website host, physical facility, security status, or service quality.
How should you read the organization and region fields?
O2BROADBAND Telefonica UK Limited is currently associated with an unknown region. These values come from public network sources and are useful lookup clues; an organization label, registration region, and actual service location may differ.
How should you verify the AS35228 result?
The page shows ASN data returned by the current upstream query; interpret it with the update time. Open representative IP pages from the same network and compare prefixes, source labels, and query times. Verify operator or service claims with the relevant registry or network operator.

Frequently asked questions about this ASN page
What does AS35228 represent?
AS35228 is an autonomous system number. The current source associates it with O2BROADBAND Telefonica UK Limited and the region field an unknown region; those values add network context but do not prove a specific service, physical location, or quality level.
What are peers, upstreams, and prefixes useful for on the AS35228 page?
They help explain the scale, interconnection depth, and route structure of AS35228. 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 AS35228?
Open a concrete IP page to check how the address maps into AS35228, then compare the prefix, source labels, and query time. Verify operator or service claims with the relevant registry or network operator.
