What is a domain?

A domain is your website's address (e.g. 166tech.az). Technically it's a name for an IP address — computers use IPs, humans use names.

How does it work?

  1. Type "166tech.az" in browser
  2. Browser asks DNS: "what IP is 166tech.az?"
  3. DNS responds: "72.61.205.54"
  4. Browser fetches site from that IP

FAQ

How long does a project take?

Simple site 7-30 days, corporate site 30-60 days, ERP/CRM 2-6 months, mobile app 2-4 months. We give exact timeline after reviewing your spec.

Why custom instead of off-the-shelf?

SaaS solutions (Bitrix, Shopify, WordPress) cover 80% of standard cases. But the 20% that doesn't fit is what makes you different from competitors. Custom invests in that 20%.

What about post-launch support?

3-6 months free support is included. After that, monthly SLA (critical bugs = 4 hours, minor fixes = 24 hours).

How do I get a quote?

Will my site rank in Google after launch?
