infrastructure hosting business

Five hundred and twelve IPv4 addresses and twenty IPv6 routes, with an exchange and a delivery network in the netnames.

What it's used for

  • A technology park's network. Two IPv4 prefixes and twenty IPv6 prefixes announced from Lebanon, five hundred and twelve addresses, across four observed BGP neighbours.

Notable

  • The IPv6 announcements climb from a /48 through /47, /46, /45, /44, /43, /42, /41 and /40, each step twice the size of the last.
  • That is ten times as many IPv6 routes as IPv4 addresses would suggest, on a holding of two /24 blocks.
  • One netname is a three-letter abbreviation for an internet exchange, the other names content delivery subnets in mixed case, so both fields describe a function rather than an owner.
  • Neither block lists the holder. The only contact on both is an operations centre belonging to another company.
  • Six addresses were queried for reverse DNS and none returned a name.

Interesting

  • The doubling staircase turns up for the third time in this stretch of numbers, here on a network with almost no IPv4 at all. It is arithmetic rather than style: any range whose edges miss a block boundary gets tiled this way.
  • An exchange and a delivery network inside one small holding is a technology park doing what it was built for. The addresses are shared infrastructure for whoever is on site, which is also why the operator's contact is somebody else's.

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 1,768 prefixes, as published 2026-10-12. 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.
