Summary

Bacloud

Lithuania · AI-generated

hosting datacenter business

The AS handle IST-AS is held by UAB Bacloud.

What it's used for

  • The address space carries hosting and data center infrastructure, evidenced by netnames like LT-BACLOUD-20050113 and reverse DNS entries such as drive-01.bacloud.online and network.bacloud.info.
  • The AS announces 18,176 IPv4 addresses across 28 prefixes and 4 IPv6 prefixes, with 13 observed neighbours, indicating a hosting provider with a moderate number of upstream connections.
  • Traffic from this AS consists of web hosting, VPS, and dedicated server endpoints for customers utilizing Bacloud's data center services in Lithuania.

Notable

  • Registrants consistently identify as BACLOUD NOC; UAB Bacloud across the majority of prefixes, aligning with the announcer.
  • The address inventory is fragmented into multiple /22 and /24 blocks, including some older allocations dating back to 2003, reflecting the growth of the data center since its inception in 2006.

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 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
