What is ip blocked system in wapkiz

is aIP address blocking configuration of a network service that blocks requests from hosts with certain IP addresses. IP address blocking is commonly used to protect against brute force attacks and to prevent access by a disruptive address. IP address blocking can be used to restrict access to or from a particular geographic area, for example, the syndication of content to a specific region through the use of Internet [1]geolocation and blocking. How it works Every device connected to the Internet is assigned a unique IP address, which is needed to enable devices to communicate with each other. With appropriate software on the host website, the IP address of visitors to the site can be logged and can also be used to determine the visitor's [2][3]geographical location. Logging the IP address can, for example, monitor if a person has visited the site before, for example to vote more than once, as well as to monitor their viewing pattern, how long since they performed any activity on the site (and set a time out limit), besides other things. Knowing the visitor's geo-location indicates, besides other things, the visitor's country. In some cases requests from or responses to a certain country would be blocked entirely. Geo-blocking has been used, for example, to block shows in certain countries. Such as censorship of shows deemed inappropriate especially frequent [4][5]in places such as China. Internet users may circumvent geo-blocking and censorship and protect personal identity and location to stay anonymous on the internet using a VPN [4]connection. On a website, an IP address block can prevent a disruptive address from access, though a warning and/or account block may be used first. Dynamic allocation of IP addresses by ISPs can complicate incoming IP address blocking, rendering it difficult to block a specific user without blocking many IP addresses (blocks of IP address ranges), thereby creating collateral [6]damage. Implementations Unix-like operating systems commonly implement IP address blocking using a TCP wrapper, configured by host access control files /etc/hosts.deny and /etc/ hosts.allow. Both companies and schools offering remote user access use Linux programs such as DenyHosts or Fail2ban for protection from unauthorised access while allowing permitted remote access. This is also useful for allowing remote access to computers. It is also used for Internet censorship. IP address blocking is possible on many systems using a hosts file, which is a simple text file containing hostnames and IP addresses. Hosts files are used by many operating systems, including Microsoft Windows, Linux, Android, and OS X. Circumvention
