'''.co''' is the [[Country Code Top-Level Domain|country code top-level domain name]] ([[ccTLD]]) for Colombia as per ISO-3166-1 code.  A government supported entity was created between [[Arcelandia S.A.]] and [[Neustar]], [[.co Internet|.CO Internet SAS]], which manages .co as an [[ccTLD#Open ccTLD|open ccTLD]].  Domain name registration is open to all entities worldwide and it is marketed as a great alternative to the [[.com]] domain space.

The '''Domain Name System Security Extensions''' is a set of [[DNS|Domain Name System]] (DNS) extensions which enables communication authentication between hosts and DNS data, while ensuring data integrity.  DNSSEC is used for securing specific information provided by [[DNS]].

An October, 2012, interview with COO [[Nicolai Bezsonoff]] put the current registration of .co at 1.35 million. [[Sedo]] has reported that .co has the highest average secondary-market price, with the first being [[.com]]. Renewal rates for domains registered during the launch period, and before general availability, are very high, well above 90%. The average rate of renewal for first and second year renewals of domains acquired during general availability is 62%.

The main goal of DNSSEC is to protect against [[Data Spoofing|data spoofing]] and corruption. Initially, it was called only [[DNS]] (Domain Name System) and did not include security extensions. The main DNSSEC extensions are specified by RFC4033, RFC4034, and RFC4035. There are also some additional [[RFC]]s which provide supporting information.  

Taco Bell, a sizeable fast-food restaurant, chose .co upon revamping its website. The company is using ta.co, and while this url currently redirects to tacobell.com, the shorter name is seen as a nod toward mobile users who wish to order customized meals online with as little inconvenience as possible.  

The DNS was initially developed without any security extensions, thus increasing the chances to get out of synch and allow the spoofing of [[IP Address|IP Addresses]] with the purpose of redirecting traffic to undesired websites. DNSSEC was created as a means of adding protection and security to the DNS so that the redirected traffic could be checked and directed towards the correct server.
