What is an IP address?<\/p>\n

<\/span>An IP address or an IP address is an address that identifies a connection to the Internet. <\/span>The IP address used for information sent on the Internet to reach the right computer.<\/p>\n

<\/span>Every Internet-connected computer has an IP address. <\/span>Sometimes multiple computers to share the same IP address.<\/p>\n

<\/span>An IP address can be dynamic or static. <\/span>A dynamic IP address is assigned through a server of the Internet service and address can be changed at each connection point. <\/span>A static IP address is always the same. <\/span>One calls it a fixed IP address.<\/p>\n

<\/span>Most ISPs only use dynamic IP addresses to private persons. <\/span>Such an IP address can thus belong to several different people from different parts of the country from one day to another. <\/span>There are few operators publish static IP addresses.<\/p>\n

<\/span>There are public and private IP addresses. <\/span>The private IP addresses are used only in local networks and should never occur in the traffic going over the Internet. <\/span><\/p>\n

<\/span>The current standard that manages IP addresses, called IPv4. <\/span>However, with an increased number of users on the network are IP addresses in IPv4 running out. <\/span>Within the next few years, most companies, organizations and operators move to the new standard IPv6. <\/span>IPv6 supports virtually unlimited number of IP addresses.<\/p>\n

<\/span>For private users is expected to transition take place relatively painlessly without the need to upgrade either the hardware or software when using a reasonably modern computer and updated operating system. <\/span>IPv4 will likely operate in parallel with IPv6 for a long time to come.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
