Summary
DALNET
business it-services turkey
DALNET-ASN is operated by DAL Bilgi Teknolojileri ve Bilisim Sistemleri Ticaret A.S.
What it's used for
- The address space carries corporate IT infrastructure and leased blocks, evidenced by netnames such as
TR-DALTR-20100920,TELNET, andGEOIPA-20210625-KAYRASYS. - With 11,008 IPv4 addresses across 23 prefixes and only 6 observed neighbours, the network functions as an internal corporate estate rather than a transit or access provider.
- Traffic from this AS consists of web and API endpoints for an IT services and consulting firm, including security and systems integration services.
Notable
- Registrants include DAL Bilgi Teknolojileri, Superonline Iletisim Hizmetleri A.S., TELNET TELEKOM HIZMETLERI ANONIM SIRKETI, and KAYRASYS SIBER GUVENLIK VE BILISIM SISTEMLERI SAN. TIC. LTD. STI., indicating a mix of owned and historically acquired or leased space.
- The inventory is finely subdivided into 23 prefixes, consistent with site-by-site segmentation for a corporate network.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
4 upstream, 1 downstream and 5 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
