About this network
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.
