About this network

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.net with per-city pool names, for example IP-ADDR-bto-03-p68.cantv.net and IP-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.
