DNS

The Blahaj Cloud DNS features provide a wide range of services relating to the working of domain names and other internet names

Authoritative DNS

Our authoritative DNS service acts as a DNS server for your domain names and reverse DNS domains. It operates in an anycast cluster currently consisting of the following locations:

Amsterdam, Netherlands
Dallas, United States
Frankfurt, Germany
Johannesburg, South Africa
Santiago, Chile
Singapore, Singapore
Sydney, Australia

All anycast instances keep their own local copy of the zone files and synchronize with a central server once a minute. If the sync fails, the old data continues being used. This makes the service resilient to outages and maintenance. If an instance goes offline, traffic is automatically re-routed to another instance.

We currently support the following record types: A, AAAA, CNAME, MX, PTR, TXT, SRV and NAPTR. We do not currently support DNSSEC.

Recursive DNS

📘
This service is in Public Beta

Our recursive DNS service allows your Compute instances to resolve domain names on the public internet. It is DNSSEC validating on demand. DNSSEC validation can be requested by setting the DO or AD bit in the query.

The service is automatically set on Compute instances via DHCP, but can also be set manually. The details are as follows:

Port 53 (TCP/UDP)
- 2.56.11.100
- 2.56.11.111
- 2a0c:6500:100::100
- 2a0c:6500:100::111
DNS over HTTPS (Port 443)

The service is only available within the Blahaj Cloud network.

DNS64

This service is in Public Beta

Our DNS64 service lets your Compute instances access the Blahaj Cloud NAT64 feature. It is only available within the Blahaj Cloud network and is not set by default. It can be used by setting the instance's DNS server to the following IP address:

2a0c:6500:100::a
