Summary
CANTV Servicios, Venezuela
isp residential legacy
CANTV is Venezuela's state-owned incumbent telephone company, and this is its main Autonomous System — the country's largest consumer internet network.
What it's used for
- Residential and small-business broadband (CANTV's ADSL service, marketed as ABA) plus dial-up-era legacy access. Subscriber prefixes resolve under
cantv.netwith per-city pool names, for exampleIP-ADDR-bto-03-p68.cantv.netandIP-ADDR-mil-06-p70.cantv.net. - CANTV's own core and data-centre infrastructure, which resolves separately (
.core.cantv.net,.datacenter..cantv.net,.gw.cantv.net).
Notable
- Roughly 2.5 million IPv4 addresses across several hundred prefixes, nearly all of it end-user access space. An IP here is a Venezuelan consumer or small business, not a server.
- CANTV was nationalised in 2007, so this is a government-owned network carrying ordinary eyeball traffic. Treat it as an ISP, not as a government network.
Interesting
- The rDNS labels encode the serving exchange (
bto,mil,cha, and others), which makes CANTV one of the easier large ISPs to break down by city purely from reverse DNS.

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
5 upstream, 24 downstream and 30 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 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 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.
