花生壳

Peanut shell, known in Chinese as 花生壳 and operated by Oray, is a dynamic DNS (DDNS) service designed to give devices on a changing public IP address a stable, mEMOrable hostname. Instead of tracking a fluctuating IP manually, users register a domAIn or subdomain through the service and let a CLIent or router update the DNS record whenever the address changes. It is General networking infrastructure rather than a Generative AI product, but it APPears in AI tool directories because self-hosted AI services, model endpoints, and remote workstations often need consistent reachability from outsIDE a local network.

What it does

At its core, Peanut Shell links a hostname to an IP address that may change over time. A small client, router integration, or Embedded firmware detects the current public address and pushes an update to Oray's DNS servers. Visitors then reach the intended machine by name rather than by numeric address. This pattern is useful for home servers, NAS devices, cameras, remote desktops, and small office appliances that sit behind consumer-grade internet connections.

Key capabilities

• Dynamic DNS mapping: keeps a hostname pointed at a changing public IP.
• Client and router support: updates can come from desktop software, mobile apps, or compatible router firmware, though exACT support may vary by model.
• Subdomain management: users can create and manage hostnames through an Oray account.
• Remote access scenariOS: commonly paired with port forwarding, VPN, or tunneling setups to reach services remotely.
• free tier availability: a no-cost option has historically been offered, with liMITs on domains, bandwidth, or features that may change over time.

Who it is for

Peanut Shell suits hobbyists and small teams running self-hosted services who want a simple hostname instead of memorizing an IP. It can also help developers expose a local AI Inference server or web app for Testing, provided they underStand the SECurity implications of opening services to the internet. Users who need guaranteed uptime, Enterprise SLAs, or extensive DNS management should evaluate Oray's paid plans or alternative providers.

How to get started

1. Create an Oray account and register a hostname through the Peanut Shell console.
2. Install the client on the target machine or configure DDNS in a compatible router.
3. Confirm the DNS record resolves to your current public IP.
4. Configure port forwarding or a tunnel so the intended service is reachable, and secure it with authentication and firewalls.

Pricing and access caveat

A free DDNS tier is the main draw, but feature limits, domain quotas, and paid upgrades may vary and should be confirmed on the official site. Because the interface and documentation are primarily in Chinese, English-speaking users may need translation help. Exposing internal services cARRies real risk; review security settings carefully before publishing anything publicly.
