AS21391 TDA-AS
Unclassified AFRINIC
Summary
Tele Diffusion d'Algerie
broadcasting government algeria media
The AS handle TDA-AS is held by Tele Diffusion d'Algerie (TDA), the Algerian state broadcasting corporation.
What it's used for
- The address space is registered under the netname
ORG-Ab1-AFRINICfor the Algerian Broadcasting entity, indicating usage for national media infrastructure. - The network announces 4096 IPv4 addresses within a single /20 prefix (80.246.0.0/20) and maintains only 1 observed neighbour, a ratio consistent with a dedicated internal or access network rather than a transit provider.
Notable
- The RDAP registrant matches the registry holder, confirming the space is directly owned by the broadcasting organization.
- The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes, reflecting a focused allocation for specific broadcast operations.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
