Domain names, web hosting, DNS, SSL, and the digital infrastructure behind everything online — explained plainly, from registrar to server to launch.
Short beats long. .com is king (95% of type-in traffic). Avoid hyphens and numbers. Say it out loud — can someone spell it after hearing it once? Check social-handle availability too. Use Namecheap or GoDaddy instant search.
Premium domains sell for $1K-$1M+. Two-word .com domains are the sweet spot. Industry keyword + location (austinplumber.com) has clear value. Check recent sales at NameBio.com. Find expired names at ExpiredDomains.net.
.com: default, most trusted. .org: nonprofits, open source. .net: tech, networks. .io: startups ($50+/yr). .co: startup alternative. .ai: AI companies ($80+/yr). ccTLDs: .us, .uk, .ca for local targeting.
DNS translates names to IP addresses. A: domain → server IP. CNAME: subdomain → another domain. MX: email routing. TXT: verification. TTL: how long records cache. Use Cloudflare for free DNS management.
