Summary
Inter.link GmbH
transit legacy
INTERDOTLINK is the backbone of Inter.link GmbH, a Berlin-based network operator selling IP transit and Ethernet connectivity across Europe.
What it's used for
- IP transit sold to ISPs, hosters and enterprises, provisioned self-service through a portal and API rather than by traditional sales cycle.
- Flex Ethernet / wavelength connectivity between European data centres, plus baseline DDoS protection for transit customers.
Notable
- A transit backbone, so most of the traffic under this ASN belongs to other people's networks. Its own directly-assigned address space is small relative to the routes it carries.
- Heavily peered: Inter.link is present at DE-CIX, AMS-IX, LINX, BCIX, VIX, SwissIX, Netnod-area exchanges and others, and reaches hundreds of European data centres.
Interesting
- Inter.link is a certified B Corporation and markets its network on sustainability and carbon-neutral operation — an unusual positioning for an IP transit provider.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 431 networks and 1,775 prefixes, as published 2026-10-11. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
