DNS (Domain Name System)

DNS (Domain Name System) is the system that translates human-readable domain names (like pool.kryptex.com) into numerical IP addresses that computers use to communicate. It works like a phone book for the internet — you look up a name and get an address.

How DNS works

1. You type a domain name in your browser or mining software
2. Your computer queries a DNS resolver (usually provided by your ISP or a public service like 8.8.8.8)
3. The resolver finds the IP address associated with the domain
4. Your computer connects to that IP address

DNS and mining

DNS problems are a common cause of pool connection failures:

• DNS resolution failure — the mining software can't find the pool server's address; connection times out
• Slow DNS — high DNS lookup latency can cause initial connection delays
• ISP DNS blocking — some ISPs or countries block certain domains at the DNS level

Fix: Switch to a reliable public DNS server:

• Google: 8.8.8.8 and 8.8.4.4
• Cloudflare: 1.1.1.1 and 1.0.0.1
