IP address blocking

Source: Wikipedia, the free encyclopedia.

IP address blocking or IP banning is a configuration of a

brute force attacks and to prevent access by a disruptive address. It can also be used to restrict access to or from a particular geographic area; for example, syndicating content to a specific region through the use of Internet geolocation.[1]

IP address blocking can be implemented with a

DHCP lease
renewal.

How it works

Every device connected to the Internet is assigned a unique

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

geolocation 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 censoring shows deemed inappropriate. This is especially frequent in places such as China.[4][5]

Internet users may circumvent geo-blocking and censorship and protect their personal identity using a

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

Terms of Services
usually reserve the right of their admins to block access at own discretion, enabling them to create collateral damage this way.

Implementations

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 unauthorized 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.
