Twenty IPv6 prefixes against a single IPv4 /22, nine of them doubling in size until they tile a /40.

What it's used for

  • Internet access. 1,024 IPv4 addresses in one /22, twenty announced IPv6 prefixes, and one observed BGP neighbour.

Notable

  • Nine of the IPv6 announcements step up in size: 2a06:8804::/48, 2a06:8804:1::/48, then /47, /46, /45, /44, /43, /42 and /41, each block twice the one before it.
  • Added together those nine cover 2a06:8804::/40 exactly, with nothing left over and nothing overlapping.
  • A separate 2a06:8800::/30 sits alongside them, and does not contain the 8804 blocks — a /30 at 8800 reaches only as far as 8803.
  • The one IPv4 block is 185.118.252.0/22, netname IL-LAN-WAN-20150925, registered to LAN-WAN I.T LTD.

Interesting

  • Nine prefixes to describe one /40 is eight more than the space needs. That staircase is what a range-to-prefix conversion emits when it walks forward from the start doubling as it goes, rather than recognising that the whole range is already a single aligned block.
  • The same staircase appears at AS12491, also Israeli, tiling a /38 with ten blocks. Two independent networks producing the identical artefact points at a shared tool or a shared habit rather than a coincidence.
  • Twenty IPv6 prefixes against 1,024 IPv4 addresses inverts the usual ratio for a network this size.

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 1,784 prefixes, as published 2026-10-19. 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.
