Summary

Gen Digital

Ireland · AI-generated

business security corporate legacy

SYMANTEC-CORP is the autonomous system for Gen Digital, formerly known as Symantec and NortonLifeLock.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames such as SYMC-143-127 and Symantec-Net associated with registrants like Gen Digital Inc. and NortonLifeLock Ireland Limited.
  • The AS announces 1280 IPv4 addresses across 4 prefixes and maintains 5 observed neighbours, a ratio consistent with an internal corporate estate rather than a transit or access provider.

Notable

  • Registrants align with the announcer, listing Gen Digital Inc. and NortonLifeLock Ireland Limited for the four announced prefixes.
  • The operator has undergone significant corporate restructuring, evolving from Symantec Corporation to NortonLifeLock Inc. and subsequently to Gen Digital Inc.
  • The inventory consists of four distinct IPv4 blocks, including a /23 and three /24s, all located in Ireland.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
