Building IPDrift.com: A Complete Case Study from Concept to Deployment

Introduction

IPDrift.com is a modern IP address intelligence platform that provides real-time geolocation data, network information, and security insights. This case study walks through the entire journey of building and deploying this application, from initial concept to production release.

The Problem Statement

In today's digital landscape, understanding IP address information is crucial for:

• Security teams detecting potential threats
• Developers debugging network issues
• Marketers analyzing user demographics
• System administrators monitoring traffic patterns

While several IP lookup tools exist, most suffer from:

• Cluttered interfaces with excessive ads
• Limited API access
• Slow response times
• Lack of modern features like dark mode and mobile optimization

We set out to build a clean, fast, and developer-friendly IP intelligence platform.

Project Goals

Primary Objectives

1. Fast Response Times: Sub-100ms API responses
2. Clean UX: Minimalist interface without ads
3. Developer-Friendly: Well-documented API
4. Mobile-First: Responsive design for all devices
5. Privacy-Focused: No tracking, no data retention

Success Metrics

• Page load time < 1 second
• 99.9% uptime
• API response time < 100ms
• Mobile lighthouse score > 90

Development Process

Phase 1: Planning & Design (Week 1)

Wireframing

• Created low-fidelity wireframes in Figma
• Focused on single-page application design
• Emphasized the search box as primary CTA

Database Selection

• Evaluated MaxMind GeoLite2 vs commercial APIs
• Chose GeoLite2 for cost-effectiveness and accuracy
• Implemented Redis caching to reduce database queries

Phase 2: Core Development (Weeks 2-3)

Frontend Implementation

// IP Lookup Component
'use client';

import { useState } from 'react';

export default function IPLookup() {
  const [ip, setIp] = useState('');
  const [data, setData] = useState(null);
  const [loading, setLoading] = useState(false);

  const handleLookup = async () => {
    setLoading(true);
    try {
      const res = await fetch(`/api/lookup?ip=${ip}`);
      const result = await res.json();
      setData(result);
    } catch (error) {
      console.error('Lookup failed:', error);
    } finally {
      setLoading(false);
    }
  };

  return (
    <div className="lookup-container">
      <input
        type="text"
        value={ip}
        onChange={(e) => setIp(e.target.value)}
        placeholder="Enter IP address..."
      />
      <button onClick={handleLookup} disabled={loading}>
        {loading ? 'Looking up...' : 'Lookup'}
      </button>
      
      {data && <IPDetails data={data} />}
    </div>
  );
}

Backend API Development

// API Route: /api/lookup
import { NextRequest, NextResponse } from 'next/server';
import { Reader } from '@maxmind/geoip2-node';
import { redis } from '@/lib/redis';

export async function GET(request: NextRequest) {
  const ip = request.nextUrl.searchParams.get('ip');
  
  if (!ip) {
    return NextResponse.json(
      { error: 'IP address required' },
      { status: 400 }
    );
  }

  // Check cache first
  const cached = await redis.get(`ip:${ip}`);
  if (cached) {
    return NextResponse.json(JSON.parse(cached));
  }

  // Lookup in GeoIP database
  try {
    const reader = await Reader.open('/data/GeoLite2-City.mmdb');
    const response = reader.city(ip);
    
    const data = {
      ip,
      country: response.country?.names?.en,
      city: response.city?.names?.en,
      latitude: response.location?.latitude,
      longitude: response.location?.longitude,
      timezone: response.location?.timeZone,
      isp: response.traits?.isp,
    };

    // Cache for 24 hours
    await redis.setex(`ip:${ip}`, 86400, JSON.stringify(data));

    return NextResponse.json(data);
  } catch (error) {
    return NextResponse.json(
      { error: 'Invalid IP address' },
      { status: 400 }
    );
  }
}

Phase 3: Features & Polish (Week 4)

import { expect, test } from '@jest/globals';

test('API returns valid IP data', async () => {
  const response = await fetch('http://localhost:3000/api/lookup?ip=8.8.8.8');
  const data = await response.json();
  
  expect(data.country).toBe('United States');
  expect(data.latitude).toBeCloseTo(37.4056, 1);

Challenges & Solutions

Challenge 1: GeoIP Database Size

Problem: MaxMind database is 60MB, too large for serverless functions.

Solution:

• Used Vercel's persistent storage
• Implemented lazy loading
• Cached frequently accessed IPs in Redis

Challenge 2: API Rate Limiting

Problem: Risk of abuse without rate limiting.

Solution:

// Implemented token bucket rate limiter
import { Ratelimit } from '@upstash/ratelimit';

const ratelimit = new Ratelimit({
  redis,
  limiter: Ratelimit.slidingWindow(10, '10 s'),
});

export async function middleware(request: NextRequest) {
  const ip = request.ip ?? '127.0.0.1';
  const { success } = await ratelimit.limit(ip);
  
  if (!success) {
    return NextResponse.json(
      { error: 'Too many requests' },
      { status: 429 }
    );
  }
  
  return NextResponse.next();
}

Challenge 3: Cold Start Latency

Problem: First request after inactivity took 2-3 seconds.

Solution:

• Implemented Edge Functions
• Pre-warmed Redis connections
• Reduced bundle size by 40%
