Summary

Grupo Baladig SL

Spain · AI-generated

business isp mail madrid

PRSZ-AS is operated by Grupo Baladig SL, a Madrid-based technology services company.

What it's used for

  • The address space carries mail infrastructure, as evidenced by reverse DNS entries such as mail.grprin-133.frane.huatiba.com and mail.grprin3-69.menet.rssreview.com.
  • The AS announces 2048 IPv4 addresses across 4 prefixes with only 1 observed neighbour, indicating a small-scale access or service network rather than a transit provider.
  • Traffic from this AS consists of mail services and related technology endpoints for the operator's business operations.

Notable

  • Registrants are mixed: the largest block 185.159.40.0/22 is registered to Grupo Baladig SL, while the other three prefixes are registered to Julio Brasa Blanco under the netname ES-XNETCORE-20151109 or ES-XNETCORE-20191101.
  • The address inventory is small and fragmented, consisting of one /22 and three smaller blocks, all located in Spain.

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 1,779 prefixes, as published 2026-10-22. 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.
