T-Mobile has also configured their IPv6 servers in such a way that a single user may have their IP address change each time they restart their phone. These factors all make it nearly impossible for us to block a single vandal without causing some "collateral damage" by inadvertently range-blocking innocent users.
If you do indefinitely block an IP address, place {{blocked proxy}} (do not substitute) on its user or user talk page for tracking purposes. Shared IP addresses Before implementing a long-term block on an IP address with a long history of vandalism, please check if it is shared by performing a WHOIS and Reverse DNS lookup query on the IP ...
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 unauthorized access while allowing permitted remote access.
The special behaviour for this type of addresses, as required at that time, [5] was lifted in 2006 and the block returned to regular global unicast. [6] In October 2005, the IETF reserved the address block fc00::/7 for use in private IPv6 networks and defined the associated term unique local addresses. [1]
The main remaining problem for Mac OS X was the presence of rogue routers, such as wrongly configured Windows Internet Connection Sharing devices pretending to have IPv6 connectivity, while 6to4 tunneled IPv6 traffic is blocked at a firewall. [citation needed] Another problem was pre-10.50 versions of Opera. [citation needed]
A hard IP address block (account creation blocked, apply block to logged-in users from this IP address) disables all editing and account creation from behind the blocked IP address, whether they be attempted anonymously or using an account (with the exception of accounts that are IP-block exempt). This is typically used when the level of ...
Address block Address range Number of addresses Scope Description ... Formerly used for IPv6 to IPv4 relay [8] (included IPv6 address block 2002::/16). 192.168.0.0/16
A1: A block prevents a user account, an IP address, or a range of IP addresses from editing Wikipedia, either partially or entirely. Blocked users can still open, access, and read any article or page on Wikipedia; they just cannot modify or edit any pages that are restricted by the block.
