Network type: residential

AS19165 announces 24 IPv4 prefixes covering 523,776 addresses and 17 IPv6 prefixes.

About this network

The AS handle WEBPASS is held by GFiber (formerly Webpass Inc.).

What it's used for

• The address space carries residential broadband traffic, evidenced by reverse DNS records pointing to cab.webpass.net (cable) and netnames like SAN-DIEGO-3, MIAMI-4, and LAS-1 indicating regional access infrastructure.
• With 523,776 IPv4 addresses announced across 24 prefixes and 27 observed neighbours, the ratio suggests a large access network providing last-mile connectivity rather than a transit provider.

Notable

• All sampled registrants are listed as Webpass Inc., which aligns with the AS holder, though the brand has since transitioned to GFiber.
• The operator was rebranded from Webpass to GFiber, a change reflected in current web presence and PeeringDB listings while registry records retain the legacy name.
• The inventory is dominated by large /15 and /16 blocks in the 136.24.0.0/15 range, with smaller /20 and /21 blocks scattered across other ranges, indicating a consolidated core estate with some legacy or acquired segments.
