Summary
Sprint (SprintLink), now Cogent Communications
transit legacy
The legacy SPRINTLINK backbone — historically Sprint's global internet
transit network — now owned and operated by Cogent Communications.
What it's used for
- A long-haul IP transit backbone. Cogent acquired the former Sprint wireline business (including SprintLink) in 2023.
Notable
- A Tier 1 transit network rather than an eyeball ISP. One of the internet's original backbones.
Interesting
- Registered in 1991, AS1239 is a genuinely early allocation from the commercial internet's formative years, even though its owner has since changed.
