Oltre a essere titolare dei registri con autorità di due dei principali domini di primo livello, <a href="/wiki/.com" title=".com">.com</a> e <a href="/wiki/.net" title=".net">.net</a>, l'azienda gestisce in appalto i domini di primo livello <a href="/wiki/.name" title=".name">.name</a> e <a href="/wiki/.gov" title=".gov">.gov</a>, nonché i domini con codice paese <a href="/wiki/.cc" title=".cc">.cc</a> (<a href="/wiki/Isole_Cocos_e_Keeling" class="mw-redirect" title="Isole Cocos e Keeling">Isole Cocos e Keeling</a>) e <a href="/wiki/.tv" title=".tv">.tv</a> (<a href="/wiki/Tuvalu" title="Tuvalu">Tuvalu</a>). Inoltre è il principale appaltatore tecnico, per i rispettivi operatori di registro (che sono <a href="/wiki/Organizzazione_non_a_scopo_di_lucro" title="Organizzazione non a scopo di lucro">Organizzazione non a scopo di lucro</a>), dei <a href="/wiki/Domini_di_primo_livello" class="mw-redirect" title="Domini di primo livello">domini di primo livello</a> <a href="/wiki/.edu" title=".edu">.edu</a> e <a href="/wiki/.jobs" title=".jobs">.jobs</a> – ruolo in cui, oltre a ospitare i domini stessi, provvede alla manutenzione dei relativi file di zona<sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup>. Gli operatori di registro equivalgono ai “grossisti” ("wholesaler") dei nomi di dominio, mentre i registrar fungono da “dettaglianti” (“retailer”), perché lavorano direttamente con il cliente finale alla registrazione di un indirizzo di dominio. </p><p>Verisign gestisce anche due dei tredici “server radice” contraddistinti dalle lettere A-M (più precisamente, i server “A” e “J”)<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup>; i server radice rappresentano il vertice gerarchico del sistema dei nomi di dominio (<a href="/wiki/DNS" class="mw-redirect" title="DNS">DNS</a>) su cui si fonda la comunicazione in Rete. Un altro compito di Verisign consiste nel generare il file di zona principale, globalmente riconosciuto, e apportarvi le eventuali modifiche disposte da <a href="/wiki/ICANN" title="ICANN">ICANN</a> e sancite dal Dipartimento del Commercio statunitense. In origine le modifiche alla zona principale venivano distribuite attraverso il server radice A, ma adesso vengono diramate a tutti i tredici server attraverso un sistema di distribuzione <a href="/wiki/Ad_hoc" title="Ad hoc">ad hoc</a> gestito da Verisign – che è l'unico, fra i dodici operatori di server radice esistenti, a gestire più di un server. I server A e J sono diventati, fra l'altro, “anycast” e non fanno quindi più capo a un centro dati della società. Tale misura è stata adottata con l'obiettivo di aumentare ridondanza e disponibilità, riducendo al contempo il rischio di <a href="/wiki/Single_point_of_failure" title="Single point of failure">single point of failure</a> (disfunzione di sistema causata dall'anomalia di una sola componente). </p> <div class="mw-heading mw-heading2"><h2 id="Note">Note</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Verisign&veaction=edit&section=3" title="Modifica la sezione Note" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Verisign&action=edit&section=3" title="Edit section's source code: Note"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-annual-1"><a href="#cite_ref-annual_1-0"><b>^</b></a> <span class="reference-text"><a rel="nofollow" class="external text" href="https://www.verisigninc.com/fr_FR/company-information/about-verisign/fact-sheet/index.xhtml">Scheda Azienda</a></span> </li> <li id="cite_note-autogenerato1-2"><span class="mw-cite-backlink"><b>^</b> <sup><i><a href="#cite_ref-autogenerato1_2-0">a</a></i></sup> <sup><i><a href="#cite_ref-autogenerato1_2-1">b</a></i></sup></span> <span class="reference-text"><cite class="citation web" style="font-style:normal"> <a rel="nofollow" class="external text" href="https://web.archive.org/web/20160303232432/http://files.shareholder.com/downloads/VRSN/0x0x820575/063CB117-54A6-42F9-BB8F-7754E6E9480B/284540_Verisign_R1.pdf"><span style="font-style:italic;">Verisign - Annual report 2014</span></a> (<span style="font-weight: bolder;
