Summary

Allegronet

Israel · AI-generated

business cloud israel

The AS handle ALLEGRO is held by Allegronet Ltd.

What it's used for

  • The address space carries business and cloud services, evidenced by the netname IL-ALLEGRO-20151117 for the primary block and the registrant identity as a provider of cloud-based services for businesses in Israel.
  • The AS announces 1280 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio that indicates an access or endpoint network rather than a transit provider.
  • Traffic from this AS consists of web and API endpoints for business clients utilizing Allegronet's cloud infrastructure.

Notable

  • Registrants for the two announced prefixes differ: ALLEGRONET LTD holds the /22 block, while Virtuozzo Inc. holds the /24 block under the netname ADVAN.
  • The address inventory is small and fragmented, consisting of one /22 and one /24, with no IPv6 prefixes in inventory.

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.
