Eleven prefixes, every one of them beginning 212.117., announced as eleven separate routes.

What it's used for

  • The network of a Swiss service provider. 7,168 addresses across eleven IPv4 prefixes, one IPv6 prefix 2a03:380::/32, and fifty-five observed BGP neighbours.

Notable

  • Nine of the eleven blocks carry the single netname CH-BACKBONE1-990525.
  • The other two are netname BACKBONE-CH, registered to Backbone CH alone rather than to the AG.
  • Prefix sizes range from a /21 down to six separate /24s, all within 212.117..
  • First observed in the routing archive in October 2000.

Interesting

  • One netname across nine blocks of four different sizes means the label describes the customer of the allocation, not the allocation itself. The registry has been recording the same fact nine times, and the six-digit date inside it fixes that fact to 1999.
  • Announcing eleven routes for what is one contiguous region of address space is a choice with a cost, since each one occupies a slot in every router carrying a full table. Networks do this when pieces of the range need different paths, or when nobody re-aggregated after the range grew.
  • Two blocks are registered to a shortened form of the company name with no legal suffix, and those are exactly the two with the other netname. The pair travelled together through whatever event produced them.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
