;Routing: Network address translation can be used to mitigate IP address overlap.<ref>{{cite web | title=Using NAT in Overlapping Networks | url=https://www.cisco.com/c/en/us/support/docs/ip/network-address-translation-nat/13774-3.html | date=August 2005}}</ref><ref>{{cite web | title=VPNs with Overlapping Subnets Problem Scenario | url=https://www.juniper.net/documentation/en_US/release-independent/nce/topics/concept/lan2lan-vpn-jseries-srx-series-overview.html | date=September 2017}}</ref> Address overlap occurs when hosts in different networks with the same IP address space try to reach the same destination host. This is most often a misconfiguration and may result from the merger of two networks or subnets, especially when using RFC 1918 [[private network]] addressing. The destination host experiences traffic apparently arriving from the same network, and intermediate routers have no way to determine where reply traffic should be sent to. The solution is either renumbering to eliminate overlap or network address translation.

;Load balancing: In [[client–server]] applications, [[Load balancing (computing)|load balancers]] forward client requests to a set of server computers to manage the workload of each server. Network address translation may be used to map a representative IP address of the server cluster to specific hosts that service the request.<ref>{{cite IETF |title=Load Sharing using IP Network Address Translation |date=August 1998 |last1=Srisuresh |first1=Pyda |last2=Gan |first2=Der-Hwa |RFC=2391}}</ref><ref>{{cite web | title=What Is Layer 4 Load Balancing? |url=https://www.nginx.com/resources/glossary/layer-4-load-balancing | date=June 2020}}</ref><ref>{{cite web | title=What is load balancing? |url=https://nfware.com/blog-what-is-load-balancing | date=November 2018}}</ref><ref>{{cite web | title=Configure Server Load Balancing Using Dynamic NAT |url=https://www.cisco.com/c/en/us/support/docs/ip/network-address-translation-nat/200608-Server-Load-Balancing-Using-Dynamic-NAT.html | date=June 2018}}</ref>
