1. Quick Start Guide

DomainCatchPro is a native 64-bit Windows desktop software suite designed to automate the acquisition of expiring domain names across three major registrars: OnlineNIC, GoDaddy, and ResellerClub.

1. Download Installer: Obtain the setup package (e.g. SetupDomainCatchProOnlineNIC.msi).
2. Install on PC: Double-click the .msi and follow the setup wizard. Standard desktop and Start Menu shortcuts will be created.
3. Run Application: Launch the application from your desktop. The software automatically starts in [Free Evaluation Mode].
4. Configure Credentials: Enter your registrar API credentials and save.
5. Upgrade to Pro: Click the License button to view your 16-character Machine ID and enter your Pro key.

2. System Requirements

• Operating System: Windows 10 (64-bit), Windows 11 (64-bit), or Windows Server 2019/2022.
• Runtime: Microsoft .NET 8.0 Desktop Runtime (x64).
• RAM: 4 GB minimum (8 GB recommended for large multi-threaded drop lists).
• Network: Low-latency broadband or VPS connection (wired or datacenter connection recommended for sub-20ms registry catches).

3. Cryptographic License Activation

DomainCatchPro uses an offline, node-locked cryptographic licensing architecture. Licenses are tied to your physical machine and require zero cloud communication to remain active.

Activation Steps:

1. In the running application, click the License button in the upper right.
2. The dialog displays your unique 16-character Machine ID. Click Copy ID.
3. Submit this Machine ID during checkout or provide it to support.
4. Paste the generated Pro License Key into the License Key box.
5. Click Activate License. The window title bar will immediately update to [Licensed Pro].

Licenses are permanently saved locally at %LocalAppData%\DomainCatchPro\license.json.

4. OnlineNIC Edition User Manual

The OnlineNIC edition connects directly to OnlineNIC's EPP server and HTTP/XML gateway for high-speed automated domain registration.

OnlineNIC Account Setup:

1. Log into your OnlineNIC Reseller Portal.
2. Ensure your account has sufficient deposit funds for pending registrations.
3. Navigate to API Management → IP Whitelist and add the public IPv4 address of your computer or VPS.
4. Note your OnlineNIC Customer ID, API Username, and API Password.

Configuring DomainCatchPro for OnlineNIC:

Open the application and fill out the configuration fields:

• Server URL / IP: OnlineNIC primary EPP / API gateway.
• API Username & Password: Your authenticated reseller credentials.
• Registrant & Admin Handles: Pre-created OnlineNIC contact handle IDs.
• Primary & Secondary Nameservers: Your target DNS servers (e.g., ns1.yourdomain.com).

5. GoDaddy Edition User Manual

The GoDaddy edition automates domain registrations through GoDaddy's official Developer REST API.

Generating GoDaddy Developer API Keys:

1. Visit developer.godaddy.com/keys and log in with your GoDaddy account.
2. Click Create New API Key.
3. Select Production environment.
4. Copy your Key and Secret.

6. ResellerClub Edition User Manual

The ResellerClub edition is built for domains registered through the LogicBoxes / ResellerClub reseller ecosystem.

ResellerClub API Configuration:

1. Log into your ResellerClub Control Panel.
2. Go to Settings → API.
3. Click Add API Key and copy your key.
4. Under Whitelisted IPs, add your current server or desktop public IP address.
5. In DomainCatchPro, enter your Reseller ID and API Key.

7. Precision Drop Catching Strategy & Technical Realities

Expiring domains pass through a standardized ICANN deletion cycle (Grace Period → 30-day Redemption Period → 5-day PendingDelete). Once deleted by the registry, domains become available for registration in high-velocity daily drop batches.

7.1 Daily Drop Windows:

• .COM / .NET (Verisign Registry): 18:00 to 19:30 UTC (approx. 1:00 PM to 2:30 PM US Eastern). Domains drop sequentially in alphabetical/hash clusters throughout this window.
• .ORG (Public Interest Registry): 14:00 to 15:00 UTC (approx. 9:00 AM to 10:00 AM US Eastern).
• ccTLDs (e.g. .co, .io, .in): Vary based on individual national registry policies (often midnight UTC).

7.2 Understanding Network Latency to Registrars

Unlike web browsing, automated drop catching is a race measured in milliseconds. When DomainCatchPro runs:

1. Your computer sends a TCP request to your registrar's API (OnlineNIC, GoDaddy, or ResellerClub).
2. The registrar's server receives the request, validates your API token and account balance, and generates an internal EPP <domain:create> packet.
3. The registrar transmits the EPP command to the central registry (e.g. Verisign).
4. The registry processes whichever registrar's create packet reached their queue first.

If your computer is connected via residential broadband, your round-trip packet latency to the registrar may be 50ms–150ms+. This latency delay is standard for all client-side tools across the industry.

7.3 The "Registrar Swarm" Reality: Why 4-Character .com (LLLL.com) Are Dominated by Mega-Services

It is essential to have realistic expectations regarding contested, tier-1 domain names:

• How Mega-Services Operate: Services like DropCatch.com and SnapNames do not use a single registrar account. Instead, they operate networks of hundreds or thousands of ICANN-accredited registrar tags ("registrar swarms"). These swarms maintain persistent, high-capacity, co-located EPP socket connections that flood the Verisign registry with tens of thousands of concurrent create commands per millisecond.
• 4-Character .com (LLLL.com) & 1-Word Names: Because all liquid 4-character .com and dictionary words have guaranteed resale value, mega-services deploy their full swarms against them every single day. An individual desktop user operating through a single registrar API will statistically almost never beat a 1,000-registrar swarm on these specific names.
• Our Honest Recommendation: If you are pursuing a heavily contested 4-character .com or one-word English dictionary domain, you should place a backorder with a dedicated multi-registrar service like DropCatch.com or SnapNames.

7.4 Where DomainCatchPro Excels & Delivers Maximum ROI

DomainCatchPro provides massive advantages for the other 95% of expiring domains:

• Brandables & Coined Names: 2-word combinations, inventive brand names, and niche project domains that drop-catch pools don't target.
• Expired Web Traffic & SEO Value: Dropping domains from defunct businesses, local companies, blogs, and content sites with established backlinks and organic traffic.
• 100% Target Confidentiality: When you place a backorder on public platforms, your target domain is published or tracked, often triggering public auctions and price gouging. With DomainCatchPro, your drop list is stored 100% locally on your computer—nobody knows what you are targeting.
• Zero Backorder Markup ($10–$15 Wholesale vs $69+ Backorder Fees): When you catch a domain through DomainCatchPro, you pay only the standard registrar registration fee (typically $10 to $15 at OnlineNIC or ResellerClub wholesale). You save $50 to $70+ per domain compared to backorder service fees.

7.5 Operational Pre-Drop Checklist:

1. Synchronize your Windows clock using an authoritative NTP time server: run w32tm /resync from PowerShell.
2. Verify your prepaid reseller account deposit has sufficient funds to cover wholesale registrations.
3. Pre-configure and save your default nameservers and registrant contact handle IDs in the application.
4. Set the schedule to start monitoring 60 seconds before the targeted registry drop window.

8. Troubleshooting & FAQ

Error: "Connection Refused / Unauthorized IP"

Most common with OnlineNIC and ResellerClub. Verify that your current public IP address has been whitelisted in your registrar control panel. (Note: Residential dynamic IPs may change on router restarts).

Error: "Insufficient Funds"

Registrars reject drop registration commands if your prepaid reseller balance is lower than the wholesale registration price of the TLD.

Migrating to a New PC:

If you purchase a new computer, open DomainCatchPro on the new computer, copy the new Machine ID, and email support with your purchase invoice to receive your updated license key.
