Summary
Virtela
business vpn ntt legacy
ASNBLK-VTLA2 is held by NTT Global Networks Incorporated, operating as the legacy Virtela network.
What it's used for
- The address space carries corporate and managed network infrastructure, evidenced by netnames like
VRTL-NET-1andVIRTELA-HONG-KONG-CN-NET, and reverse DNS entries pointing tovirtela.net. - With 1536 IPv4 addresses across 6 prefixes and only 1 observed neighbour, the inventory suggests a small, self-contained corporate estate rather than a transit or access provider.
Notable
- Registrants align with the announcer, listing NTT Global Networks Incorporated and IRT-VIRTELA-AP for the respective US and Asia-Pacific blocks.
- Virtela was acquired by NTT, which now operates the network under the NTT Global Networks brand while retaining the original Virtela identity in many technical records.
- The inventory consists of six /24 blocks, including two in the 119.31.0.0/16 range associated with Hong Kong, indicating a geographically distributed but small footprint.

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 1,782 prefixes, as published 2026-10-16. 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.
