business translation localization corporate

PL-LIONBRIDGE is held by Lionbridge Technologies, Inc.

What it's used for

  • The address space carries corporate infrastructure for a translation and localization services provider, as indicated by the netnames US-LIONBRIDGE-20170823 and PL-LIONBRIDGE-LAN-2.
  • The AS announces 768 IPv4 addresses across 2 prefixes with 4 observed neighbours, a ratio consistent with a business network rather than a transit or access provider.
  • Traffic from this AS consists of office workers and web/API endpoints supporting Lionbridge's global language services operations.

Notable

  • Registrants align with the announcer, listing Lionbridge Technologies, Inc. and Abuse-C Role for both prefixes.
  • Lionbridge Technologies rebranded to simplify its business focus, continuing to operate as a leading provider of translation and localization services.
  • The inventory consists of two contiguous IPv4 prefixes in the 185.218.156.0/23 and 185.218.158.0/24 range, with no IPv6 prefixes announced.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
