Topology (CAIDA AS Rank)

The network's position in the inter-domain routing hierarchy: its customer cone, connectivity, and transit role.

Customer cone

115

ASes reachable as customers

AS rank

#433

by customer-cone size (1 = largest)

Connectivity

1 providers · 0 peers · 3 customers

Transit role

Transit / access

carries traffic for downstream customers

Upstream providers

Settlement-free peers

Downstream customers

Peering & transit neighbours (CAIDA)

Inferred AS-level relationships: 1 upstream providers, 0 peers and 3 downstream customers. The graph shows the largest few of each; the lists link through.

Upstream providers1

give this network transit

AS3356 LEVEL3 - Level 3 Parent, LLC

Settlement-free peers0

exchange traffic directly

None recorded.

Downstream customers3

buy transit from it

Relationships are inferred from BGP by CAIDA and refreshed monthly. Transit links are well captured; some private and IXP peering is under-observed, so peer counts are a lower bound.

IPv6 deployment

Measured share of this network's users reaching the Internet over IPv6 (APNIC end-user measurement, United States).

IPv6 capable

0.0%

users that can reach IPv6-only content

IPv6 preferred

0.0%

users that use IPv6 when both are offered

Capable0.0%

Has working IPv6 connectivity, even if it isn't always chosen.

Preferred0.0%

IPv6 wins when a destination is dual-stacked — the real-world usage rate.
