Residential AFRINIC Cable/DSL/ISP
Summary
Sentech
cable dsl isp south-africa
The AS handle INFOSAT-IP is held by Sentech SOC Ltd.
What it's used for
- The address space carries residential and business access traffic, evidenced by the reverse DNS record
myw-stp-66-18-82-0.sentechsa.netwhich indicates a static IP assignment within the Sentech network. - The AS announces 7936 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining 15 observed neighbours. This ratio of address space to peering partners is consistent with an access or eyeball network rather than a transit provider.
Notable
- All five announced IPv4 prefixes are registered to Sentech SOC Ltd under the netname ORG-IL12-AFRINIC, confirming that the registrants align with the AS announcer.
- The address inventory is concentrated in the 66.18.64.0/20 block and its subdivisions, representing a contiguous corporate estate managed by the operator.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 448 networks and 1,851 prefixes, as published 2026-11-04. 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.
