Domain Validated SSL
/domain-validated-sslDomain Validated SSL — is also called personal. This certification needs checking a primary level domain. To get this certificate, it’s enough to prove your ownership of the domain. You can stand the test through email validation by following the link in an email to one of the domain email addresses, or through HTTP validation by placing certain file in domain root directory.
Extended Validation SSL

Wildcard SSL

When using Wildcard SSL, you get SSL certificate for a group of subdomains .domain.*() allows to use this certificate for any number of subdomains on unlimited number of servers.
SSL certificate
/ssl-sertifikatSSL certificate is some of the unique digital signature, or digital identity of your website, which confirms that data exchange between website and browser is conducted by secured channel. Website protection with SSL certificate allows to provide secured encrypted connection between web server (website) and web client (browser) by means of HTTPS protocol.

DNS (Domain Name System)
/test-articleWhat is DNS? DNS (Domain Name System) — is a hierarchical and decentralized naming system. It associates various information with domain names assigned to each of the participating entities and allows to identify their IP addresses. A hierarchical system is evident in the domain address structure. Each of address components divided by dots is correspond to a domain (or a zone)
DNS domain zone file
/fajl-dns-zony-domenaDNS server which is responsible for hosts name in its zone, must keep data about hosts in database and provide it by request from remote computers. DNS database is textual file, which consists of RR records. These records describe computers and their functions in local zone. To conduct data exchange with remote servers, the DNS server software (it’s usually a ‘named’ program) must be launched.
DNS resource records
/resursnye-zapisi-dnsDNS server, which is responsible for host names in its zone, must keep hosts’ data in database and give it for requests of other devices. DNS database is text file, which consists of RR records (resource records). These records describe computers and their functions in a domain zone. To start data exchange with remote DNS servers, the DNS server soft must be launched (it’s usually ‘named’
ccTLD
/cctldCountry code Top Level Domains (ccTLDs) are top-level two-letter domains, national domain zones (UA - Ukraine, KZ - Kazakhstan, BY - Belarus, US - USA, FR - France, JP - Japan, IN -India and so on). These domains are appointed by international IANA (Internet Assigned Numbers Authority) organization according to codes of countries and territories.
DNS сервер
/dns-serverWhat DNS server is and how it works? If DNS is a hierarchical and decentralized naming system, which contains data about server names (hosts) and allows to identify their IP addresses, than DNS server as a component of it is a software and hardware system, which contains necessary data about domain and provides it upon request in accordance with technical network requirements.
Subdomain
/poddomenySubdomain is a domain which is a part of a higher level domain. Technically, second level subdomains are third level domains.
MX record
/mx-zapisMX (mail exchanger) record is mail DNS record which is used for email routing in Internet. MX record of a certain domain contains the name of a mail server, that services this domain, and the serial number of its server (priority number is used if the domain services few mail servers).
Public Key
/public-keyPublic Key - Public Key is open part of key pair. This key allows viewing SSL certificate on your website. It complies with your private key.
Private Key
/private-keyPrivate Key - is the half from key pair (first half is public key). It’s used in SSL certificate. Private key should be kept in secret. It’s forbidden to send it by email, disclose or rely it to somebody.
HTTPS (HyperText Transfer Protocol Secure)
/https-hypertext-transfer-protocol-secureHTTPS protocol (HyperText Transfer Protocol Secure) is a continuation of HTTP protocol for supporting secure data exchange. It allows client and server to provide encrypted communication channel and to send messages by this channel with protection from bugging. Supports TLS/SSL encryption technology.
