Summary
Airtel Tanzania
mobile residential isp africa
airtel-tz-as is operated by Airtel Tanzania.
What it's used for
- The space carries mobile and fixed-line subscriber traffic, evidenced by reverse DNS entries such as
0-68-186-197.r.airtel.co.tzand255-71-186-197.r.airtel.co.tz. - The AS announces 64,512 IPv4 addresses across 33 prefixes and 1 IPv6 prefix, while maintaining 15 observed neighbours; this high address-to-neighbour ratio indicates an access network serving end-users rather than a transit provider.
Notable
- The RDAP registrant for the 41.75.216.0/22 prefix is listed as Airtel Tanzania, aligning with the AS holder, though most other prefixes show unknown registrants in the sample.
- The operator was formerly known as Celtel Tanzania before being rebranded as Airtel Tanzania following a change in ownership and management.
- The address inventory is dominated by the 197.186.0.0/16 range, with significant blocks in 156.158.0.0/17 and 41.75.208.0/22, reflecting a large and subdivided corporate estate.

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.
