isp business infrastructure

An AS handle written as a sentence, explaining which network the number is for.

What it's used for

  • A Russian network operator. 8,192 addresses across six IPv4 prefixes, three observed BGP neighbours, and no IPv6 announced.

Notable

  • The AS handle is ZONDH AS for RU-ZNETWORK.
  • RU-ZNETWORK-20000120 is also the netname on four of the six blocks; the other two are ZBC.
  • All six prefixes are adjacent, together covering 213.168.128.0/19 exactly.
  • Eighteen addresses were sampled and none returned a name.

Interesting

  • The handle is the only one in this range written as a phrase rather than a label, and it points at the netname. Someone treated the field as a place to explain the relationship between the AS number and the address block, which is genuinely useful information that the registry has no structured place for. It works, and nothing but convention says it should not.
  • A contiguous /19 announced as six separate prefixes of five different sizes is more announcements than the space requires. Splitting like this is usually left over from routing the pieces to different places at some point; once the announcements exist, nothing forces them back together.
  • Two /24s carved out with their own netname mark a subdivision inside a block that is otherwise registered as one.

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 1,772 prefixes, as published 2026-10-15. 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.
