The Verisign Customer Centre is an online portal for partners to find technical details on implementation, including SDKs.

Verisign operates several domain name registries; however, we are not a registrar. If your domain name has expired, please contact your registrar about renewing. If you do not know who your registrar is, you may search the Whois database for your domain name. The results will show the registrar responsible for registering your domain name so that you can contact them.

To become a registrar, you will need to go through the certification process. Different top-level domains (TLDs) have different requirements and processes. Most businesses start with .com and .net certification, then add more TLDs. Get all the details for the .com, .net, .tv, .cc, .name and .jobs certification in our Become a Registrar section.

Currently, there are 21 generic top-level domains (gTLDs), some of which are .com, .net and .name. Soon, however, ICANN will begin to approve new gTLDs and your domain name choices will increase exponentially. Learn more about new gTLDs

If you own a website or provide other Internet-based services and would like to use Internationalised Domain Names (IDNs) to help your customers, you may register an IDN in available characters through participating ICANN-accredited and Verisign-certified registrars. A registrant requests an IDN from a registrar that supports IDNs. The registrar converts the local language characters into a sequence of supported characters using ASCII-compatible encoding (ACE). The registrar submits the ACE string to the Verisign® Shared Registration System (SRS), where it is verified and encoded. The IDN is added to the appropriate TLD zone files and propagated across the Internet. Find a Registrar

A denial of service (DoS) attack occurs when traffic is sent from one host to another computer with the intent of disrupting an online application or service. A distributed denial of service (DDoS) attack occurs when multiple hosts (such as compromised PCs that are part of a “botnet”) are used to carry out and amplify an attack. Attackers usually create the denial-of-service condition by either consuming server bandwidth or impairing the server itself. Typical targets include Web servers, DNS servers, application servers, routers, firewalls and Internet bandwidth.

It uses a proprietary filtering technology to stop a DDoS attack in the cloud before it reaches a customer’s network.
