About this network

A Zenlayer network (ZEN-ECN). Zenlayer is a global edge-cloud and bare-metal provider (US-headquartered, with a large Asia-Pacific footprint) offering compute, networking, and interconnection close to end users.

What it's used for

• Edge compute, bare-metal servers, and global connectivity/CDN-style delivery, especially bridging traffic into and across Asia.

Notable

• An IP here identifies Zenlayer as the host or edge provider, not the operator of whatever runs on it.
• Zenlayer emphasizes low-latency edge locations in emerging markets where hyperscalers have thinner coverage.

Interesting

• Zenlayer built out many edge points of presence across Southeast Asia, India, the Middle East, and Africa, positioning as an on-ramp to hard-to-reach regions.
