Summary

GlobalLogic Slovakia

Slovakia · AI-generated

business enterprise hosting

A software engineering office on 256 addresses, with its provider holding the paperwork.

What it's used for

  • The network of a software engineering company's Slovak office. 256 addresses in one IPv4 prefix, a single observed BGP neighbour, and no IPv6 announced.

Notable

  • The whole inventory is 85.159.107.0/24, netname NET-GlobalLogic.
  • The block's registrant contact belongs to a different company's network administration team.
  • The AS handle drops the country and legal suffix the AS name carries.
  • First observed in the routing archive in August 2000.
  • Three addresses were sampled and none returned a name.

Interesting

  • The netname is the customer's name, the contact is the provider's. This is provider-assigned space: the block belongs to the internet provider, is labelled for whoever is using it, and stays behind when the customer leaves. An AS number is portable, address space obtained this way is not, and the two travel together only as long as the contract lasts.
  • One neighbour and 256 addresses is the smallest meaningful shape a network can have while still running BGP. The reason to bother is usually that a parent company standardises on it, so every office announces its own space regardless of size.
  • A first appearance in 2000 for a company whose current name and structure came much later. AS numbers get reassigned, and the routing archive records when the number started being announced rather than anything about who is announcing it now. Age in this data is a property of the identifier, not of the organisation holding it.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
