IP hijacking is sometimes used by malicious users to obtain IP addresses for use in spamming or a distributed denial-of-service (DDoS) attack. When a router disseminates erroneous BGP routing information, whether intentionally or accidentally, it is defined by the Internet Engineering Task Force (IETF) in RFC 7908 as a "route leak."

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.
Mirai includes a table of IP address ranges that it will not infect, including private networks and addresses allocated to the United States Postal Service and Department of Defense.
