What traffic from Netgroup Denmark means for a website
Every address in these 1 ranges belongs to Netgroup Denmark infrastructure — virtual machines, containers, load balancers or edge nodes — rather than to an end-user's broadband or mobile line. A request from one of them is therefore a server talking to your server: a crawler, a monitoring probe, an API client, a scraper or a VPN/proxy exit hosted on Netgroup Denmark.
That is why fraud and abuse systems treat datacenter origins differently from residential ones: a sign-up, a vote or an ad click from a Netgroup Denmark address is unlikely to be an ordinary person at home. The sensible response is not a blanket block (legitimate bots and corporate VPNs live here too) but a lower trust score, stricter rate limits or a challenge.
To test a single address, run it through the proxy checker: it reports the datacenter match, the announcing network and whether the address also appears on Tor or blocklists. Proxy & VPN detector →
How this page is built
Ranges come from the open datacenter list (client9/ipcat) refreshed by our cron jobs; the announcing networks are looked up in iptoasn routing data and locations in DB-IP Lite (CC BY 4.0) using one address per sampled range. Counts are recomputed daily.
