About this network

The AS handle FENACO is operated by fenaco Genossenschaft.

What it's used for

• The address space carries corporate infrastructure for fenaco, evidenced by reverse DNS entries such as dasur.fenaco.com, mailext.extern.fenaco.com, and dawth.fenaco.com.
• The network announces 512 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 45 observed neighbours. This ratio of limited address space against a high number of peering partners indicates a transit-heavy or well-connected corporate network rather than a large-scale access provider.

Notable

• Registrants for both announced IPv4 prefixes are consistent with the announcer, listing fenaco NOC and fenaco Genossenschaft.
• The address inventory is compact, consisting of two /24 blocks in the 193.200.144.0 and 195.245.237.0 ranges, alongside a single /32 IPv6 prefix.
