IBM Domain Name Services (DNS) vs. Control D

IBM Cloud offers comprehensive DNS services for both public and private applications, ensuring swift response times, outstanding redundancy, and high-level security. These services adeptly translate domain name inquiries into their respective IP addresses, simplifying domain management through a user-friendly interface or an API. IBM Cloud's DNS solutions support name resolution for virtual machines (VMs) within a VPC network and across various VPC networks. Users can personalize their DNS zones and designate specific host IPs, granting them control over which VPC networks can access particular DNS zone data. With services available in all IBM Cloud Multizone Regions, these DNS offerings are crafted for optimal availability and rapid access. Additionally, users can limit access to their DNS records to chosen VPC networks, which is vital for safeguarding GDPR-sensitive IP and hostname information. Beyond this, users have the ability to configure their zones to yield different resolved addresses based on whether queries originate from private VPCs or public networks, thereby bolstering security and adaptability. This feature allows organizations to create a customized and secure DNS infrastructure tailored to their diverse requirements, ultimately enhancing operational efficiency and data protection.

Control D is a versatile DNS filtering and traffic redirection service that utilizes advanced Secure DNS protocols such as DNS-over-HTTPS, DNS-over-TLS, and DNS-over-QUIC, while also accommodating traditional DNS. With Control D, users can effectively eliminate harmful threats, restrict various types of undesirable content across the network—including advertisements, trackers, IoT data, adult material, social media, and more—while also redirecting traffic through transparent proxies and monitoring network activities and usage patterns at a client-specific level. Consider it your own personalized Authoritative DNS resolver for the entire Internet, providing you with detailed control over which domains are allowed to be resolved, redirected, or blocked. This capability not only enhances security but also empowers users to tailor their online experience according to their preferences.
