Summary
Delta Networks (Pvt) Ltd
isp residential legacy
AS9937 (DELTANET-AS-AP) is held by Delta Networks (Pvt) Ltd, a Karachi, Pakistan internet provider. The -AP in the handle is just the APNIC region suffix and says nothing about the country: the aut-num, the org object ORG-DN1-AP, and the DELTANET-PK inetnum all carry a PK country code and the same Usman Arcade, Block 16, F.B. Area address in Karachi.
What it's used for
Delta Networks is a small local access provider, and the routing reflects that precisely. RIS sees 8 IPv4 prefixes totalling 2,816 addresses and no IPv6 at all. The bulk of it is a contiguous run of /24s out of 180.149.208.0–180.149.223.0 plus one newer APNIC allocation, 103.255.148.0/22, registered as DELTANET-PK. That is roughly 2,800 routable addresses for an entire ISP — a footprint that only works behind carrier-grade NAT, which is the norm for Pakistani broadband operators of this scale.
One observed neighbour settles the role. A single upstream means Delta Networks is a leaf network buying transit from one provider and reselling access downstream. There is no peering business here and no wholesale function; the AS exists so the company can carry its own portable APNIC space across a change of upstream.
Notable
- Easy to mistake for the Taiwanese electronics manufacturer of a similar name, or to place in Hong Kong on the strength of the
-APhandle. The registry data is unambiguous: this is a Karachi ISP. - Holds
ALLOCATED PORTABLEAPNIC space, which is why it needs an ASN at all — portable space is what lets a small ISP keep its addresses when it switches transit provider. - No IPv6 announced, consistent with a small operator that has not needed to solve address exhaustion any way other than NAT.

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.
