isp cable dsl residential

AS53115 is operated by ISPX Solucoes em Telecomunicacoes SPE Ltda.

What it's used for

  • The address space carries static residential and business customer endpoints, as indicated by reverse DNS entries such as static-203-255.ispx.com.br and static-192-064.ispx.com.br.
  • The AS announces 3584 IPv4 addresses across 5 prefixes and 40 IPv6 prefixes, while maintaining 100 observed neighbours. This ratio of moderate address space to high peering count suggests a regional access provider with significant upstream and peering relationships.
  • Traffic from this AS consists of subscriber eyeballs for cable and DSL services in the São Paulo region, consistent with the operator's classification as a regional Cable/DSL/ISP.

Notable

  • All registrants for the announced IPv4 prefixes match the AS holder, ISPX Solucoes em Telecomunicacoes SPE Ltda, with the netname 138373.
  • The IPv4 inventory is concentrated in the 187.109.192.0/21 range, subdivided into five distinct prefixes, while the IPv6 space is allocated under the 2804:4d48::/36 block.

Reputation

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: 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.
