Summary
Puerto Rico Webmasters (PRW.NET)
isp hosting legacy
ESS-PR-WEBMASTERS is Puerto Rico Webmasters, trading as PRW.NET — a San Juan-based provider that sells business internet access, web and cloud hosting across the island. RIS sees 17 IPv4 prefixes and roughly 6,100 addresses, 2 IPv6 prefixes out of 2602:faca::, and only 2 observed BGP neighbours.
What it's used for
A mix of hosting and business access, and the reverse DNS shows both halves at once. Generic pool names — pr-65-218-144-5.prwip.net, sju-69-89-43-5.prw.net (sju being San Juan's airport code) — sit alongside the operator's own machines (ws1.prw.net) and, more tellingly, alongside customer-named hosts: fw1.clandsurveyspr.com is a customer firewall on an access circuit, while www.vegabaja.pr, beta.prdigital.com and dor-69-89-35-5.doradobeachpr.com are customer web presences living inside the provider's space. That combination — customer edge devices plus customer websites — is the signature of a regional provider that grew out of web hosting into connectivity, which is exactly what the company name records.
The registrant column is clean: every prefix resolves to Puerto Rico Webmasters itself, under a mix of its own handle (PRW-11653-1) and older UUNET-era netblock names (UU-65-218-144, UU-208-249-78) inherited with the space. Nothing is registered to an unrelated third party, so none of the leased-address patterns apply.
Notable
Two BGP neighbours for a provider of this size is unusually thin, and it reflects the geography: an island network's transit choices are constrained by who lands submarine capacity, so a small Caribbean ISP ends up with far fewer adjacencies than a mainland provider of the same customer count.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, 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: 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.
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.
