SKY Serviços de Banda Larga Ltda

Brazil · AI-generated

isp legacy

AS11338 is held by SKY Serviços de Banda Larga Ltda, the broadband arm of SKY Brasil — the pay-TV operator that sells fixed internet access to Brazilian households alongside its satellite television service. This is a consumer eyeball network. RIS sees 7 IPv4 prefixes, 13,312 addresses, 7 IPv6 prefixes, and 28 observed neighbours.

What it's used for

Residential broadband subscribers. The reverse DNS is decisive and leaves no room for a competing reading: sampled addresses right across 177.13.0.0/20, 177.13.224.0/20 and 177.13.240.0/20 resolve to hostnames of the form 5-224-13-177.skybandalarga.com.br — the octets of the address itself, reversed, glued into a generated hostname under SKY's own broadband domain. Machine-generated per-address PTRs on the operator's own domain, applied uniformly across whole /20s, are the signature of an access pool handing addresses to end-user CPE, not of servers or corporate hosts.

Notable

The registrant data agrees with the holder. Every 177.13.x prefix that resolved is registered in LACNIC to SKY Serviços de Banda Larga Ltda itself, so the space is first-party throughout. One prefix, 177.55.4.0/22, failed RDAP lookup — that is a failed call, not a clearance and not a finding, and we draw nothing from it either way.

Interesting

Note the IPv6: SKY announces 7 IPv6 prefixes out of 2804:e30::/32, LACNIC space, in parallel with the v4. A residential ISP deploying v6 to subscribers is the ordinary reason to see that alongside a modest v4 pool — the v4 side is squeezed and CGNAT-pressured while v6 carries the growth. Twenty-eight observed neighbours is consistent with a Brazilian eyeball network peering at the domestic exchanges (IX.br) rather than with a transit carrier, which would show peers in the hundreds. Addresses in this AS should be read as home broadband customers in Brazil, and geolocated to the subscriber, not to SKY's head office.

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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
