AS31529 DENIC-ANYCAST-AS DNS anycast AS object for .DE DNS service
Unclassified RIPE
Summary
DENIC eG
dns registry anycast infrastructure
The AS handle DENIC-ANYCAST-AS is operated by DENIC eG, the registry for the .de top-level domain.
What it's used for
- The address space carries DNS anycast services for the .de registry, evidenced by netnames such as
DENIC-ANYCAST-V4,DENIC-ENUM-ANYCAST-v4-1, andDENIC-ANYCAST-CUSTOMER-v4-141. - The AS announces 1792 IPv4 addresses and 11 IPv6 prefixes against 201 observed neighbours, a ratio indicating a high-connectivity infrastructure role rather than a residential access network.
Notable
- All registrants for the announced prefixes are consistent with the announcer, listing "DENIC role account", "DENIC eG", and "DENIC Business Services".
- The address inventory is finely subdivided into specific functional blocks, including distinct /24s for ENUM and general anycast services, reflecting an internal corporate estate structure.

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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
