DnsTube

Having a well-structured enterprise or business can sometimes involve going past the basics and deploying a hierarchical PC naming system, especially when using a highly branched digital environment. A DNS or Domain Name System can provide such functionality, ensuring users have reachable, indexed resources across their organization, from the Internet or other protocol networks. The DNS offered by Cloudflare provides both standard, and extra functionality, through built-in DDoS mitigation and DNSSEC.

For those who have dynamic IPs, relying on the DNS services for easy identification of their machines can become quite challenging. This is where DnsTube steps in, offering users a specialized client for constantly updating the Cloudflare DNS entries with the latest IP according to the inferred dynamic changes.

The tool will perform periodic checks for the machine IPs, and when these have been dynamically changed, will adjust them in the Cloudflare DNS accordingly. In terms of the records that are updated along, one can expect the A (IPv4), AAA (IPv6), SPF, as well as TXT, to be adjusted.

Both the API keys and tokens offered by Cloudflare are supported and the aforementioned updating is carried out on a scheduled, adjustable timetable, which can be customized.
