Summary

Twister Soft Net

Brazil · AI-generated

isp residential brazil

AS52743 is operated by Twister Soft Net Ltda.

What it's used for

  • The space carries residential internet access, evidenced by the reverse DNS record 177.85.166.254.twister.com.br and the netname 198114 associated with the registrant Twister Soft Net Ltda.
  • The AS announces 1024 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with 3 observed neighbours; this low neighbour count relative to the address block indicates an access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for a Brazilian regional internet service provider, as confirmed by the Google Play listing for customer applications.

Notable

  • The RDAP registrant for the announced prefix 177.85.164.0/22 is Twister Soft Net Ltda, which matches the AS holder.
  • The address inventory consists of a single contiguous IPv4 block and one IPv6 prefix, typical of a small 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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
