telecom isp brazil residential

AS61618 is operated by Viva Tecnologia Telecomunicações LTDA.

What it's used for

  • The address space carries subscriber traffic, evidenced by reverse DNS entries pointing to vivatecnologia.com.br for both announced IPv4 blocks.
  • The AS announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 45 observed neighbours; this ratio indicates a regional access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of residential and small business internet access provided by Viva Tecnologia, a Brazilian telecommunications company focused on local connectivity services.

Notable

  • Registrants for both announced prefixes (45.231.172.0/22 and 170.81.100.0/22) match the AS holder, Viva Tecnologia Telecomunicações LTDA, with netnames 554612 and 489800 respectively.
  • The address inventory consists of two contiguous /22 blocks in the IPv4 space and a single /32 in IPv6, representing a compact and internally consistent estate for a regional ISP.

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: 442 networks and 1,772 prefixes, as published 2026-10-15. 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.
