Unclassified LACNIC
Summary
UOL
business content brazil web
AS18479 is operated by Universo Online S.A., commonly known as UOL.
What it's used for
- The address space carries corporate and web infrastructure, evidenced by reverse DNS entries such as
static.uol.com.branduol.com.br. - The AS announces 19,200 IPv4 addresses across 21 prefixes with only 1 observed neighbour, indicating a large internal corporate estate rather than a transit or access network.
Notable
- Registrants are consistent with the announcer, with most prefixes registered to Universo Online S.A. and one prefix (186.234.252.0/23) registered to DIGITALSERVICES.UOL S.A., a related entity.
- The address inventory is finely subdivided into 21 prefixes, reflecting site-by-site segmentation typical of a large corporate network.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
1 upstream, 0 downstream and 1 adjacent networks observed; most-used upstreams first.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-05, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
