DMTNET is operated by Shanghai DMT Information Network cor.,LTD.
What it's used for
- The address space is identified by the netname
DMTNETacross all announced prefixes, with registrantIRT-DMTNET-CN. - The AS announces 768 IPv4 addresses across 3 prefixes and maintains 2 observed neighbours, a ratio consistent with a small-scale business or internal network rather than a transit provider.
Notable
- All three announced prefixes (
203.176.168.0/24,203.176.170.0/24,210.5.150.0/24) share the same netname and registrant, indicating a unified ownership structure. - The inventory consists of three /24 blocks, all located in China, with no IPv6 prefixes announced.

Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-17, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,783 prefixes, as published 2026-10-17. 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.
