Summary
Cybernet (Cyber Internet Services)
isp residential transit legacy
AS9541 (CYBERNET-AP) is held by Cyber Internet Services (Pvt) Ltd — "Cybernet", a Karachi-based Pakistani internet service provider and part of the Lakson Group. Cybernet sells fibre connectivity, data-centre and cloud services to Pakistani enterprises and carriers, and runs StormFiber, its fibre-to-the-home brand. This AS is the company's principal network and carries both sides of that business.
What it's used for
RIS shows 708 IPv4 prefixes covering 224,512 addresses, 222 IPv6 prefixes, and 170 observed neighbours. The neighbour count pins down the role: 170 is far too many for a pure eyeball network of this size, which would sit in the single or low double digits, but well short of the hundreds-to-thousands a wholesale transit carrier accumulates. It is the profile of a national ISP that peers widely, sits on the local exchanges and carries a modest downstream cone of enterprise and smaller-operator customers alongside its own subscribers.
The IPv4 estate is heavily fragmented — a 153.117.0.0/16 at the top, then many /21s, /22s and /23s drawn from unrelated blocks (202.47.x, 103.26.x, 175.107.x, 72.255.x, 139.135.x, 36.255.x, 61.5.x, 192.140.x). That patchwork is what a growing ISP in a region with tight IPv4 supply ends up holding: space acquired in small pieces from APNIC and via transfers.
Notable
- The IPv6 side is the more striking number. 222 prefixes, including
/40s and/41s alongside a long tail of/48s, is far more v6 work than most networks this size have done. The pattern — large blocks for subscriber pools, individual/48s for customer sites — matches an operator serving consumers and businesses on one AS. - Cybernet is a partner in the PEACE submarine cable, giving it international capacity of its own.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
