RegZone.info DNS system

The company ZONER a.s., a provider of hosting services, operates its own autonomous DNS system, which was developed in 2009 and deployed in spring 2010 after successful testing. Since then, it has been regularly modernized to meet the highest standards for our customers' domains.

Our DNS system is designed to meet strict requirements for stability, speed, security, and server independence. It is fully scalable and ready for future expansion.

The functionality of the internet and domains is entirely dependent on DNS systems, which ensure the translation of domain names to corresponding IP addresses. If the DNS servers for a certain domain are unavailable, that domain becomes non-functional. This means that visitors cannot reach the websites, email communication is interrupted, and search engines stop indexing the domain. These are just some of the problems that can occur due to DNS failure.

Key features of our DNS system:

• Three geographically independent name servers to eliminate outages
• Option to expand to multiple servers as needed
• Server locations: twice in the Czech Republic (Prague, Brno) and once in the USA for quality response in America and Asia
• Use of hardware from DELL
• System built on NSD from NLnetLabs, which offers higher performance than Bind9
• Very quick deployment of DNS for new domains
• Ability to set TTL for individual records
• Support for IDN (Internationalized Domain Names)
• DNSSEC implementation for increased security
• Native support for IPv6 on all our name servers
• API support for partners
• Ability to mask partner DNS (aliasing)

Our name servers are designated as ns1.regzone.cz, ns1.regzone.info, and ns1.regzone.de. For .CZ domains, DNSSET:ZONER is set.

What is DNS?

The DNS (Domain Name System) is a hierarchical system of domain names realized through DNS servers and the protocol of the same name, which serves to exchange information. Its main task is to convert domain names into the IP addresses of network nodes. Over time, however, it has gained additional functions, for example, for email and IP telephony, and today serves as a distributed database of network information.
