AS203729 is utilized as an infrastructure network. Announcements made by AS203729 are used for network infrastructure and network infrastructure support; no services are hosted on it. AS203729 interconnects with transits, AS42615, and on various internet exchanges, including:

AS203729 is open to peer with all networks present on any mutual exchange. AS203729 generally announces the same prefixes to the route server that are announced to direct peers; as a result, a direct session is often unnecessary.


AS42615 is utilized as an access network. Announcements made by AS42615 are used for both end-user access and hosting of content.

AS42615 interconnects with transits and AS203729. Direct peering is not available as all routes which would be announced via a peering link are announced through AS203729.

General Policy

Both ASNs operate strict route filtering; filters are regenerated every 24 hours from RPKI/IRR. Prefixes smaller than a /24 (v4) or /48 (v6) will be filtered.

RPKI (on all prefixes except those provided by AMPRnet) and IRR entries are present for all announced prefixes (under the AS-SET AS-IGLOO22225). Static filters are used on all exported prefixes.

Neither AS42615 nor AS203729 are used as "research" or "experimental" networks. Both are responsible for production traffic (such as this website!).
