Summary

Banco Avanz S.A.

Nicaragua · AI-generated

banking business nicaragua

AS27811 is operated by Banco Avanz S.A., a financial institution in Nicaragua.

What it's used for

  • The address space is registered under the netname 165.98.0.0 - 165.98.255.255 with registrant CENTRO DE ADMINISTRACION NIC.NI, indicating the space is allocated by the national registry rather than carrying specific customer-facing reverse DNS records.
  • The AS announces 512 IPv4 addresses within a single prefix (165.98.44.0/23) and maintains only 1 observed neighbour, a ratio consistent with a small, self-contained corporate network rather than a transit or access provider.

Notable

  • The registrant CENTRO DE ADMINISTRACION NIC.NI differs from the AS holder Banco Avanz S.A., reflecting the standard allocation process where the national registry holds the address block for the local operator.
  • The inventory consists of a single contiguous /23 block, representing a compact internal estate typical of a corporate headquarters or primary data center.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
