===Addressing conflicts===
An IP address conflict occurs when two devices on the same local physical or wireless network claim to have the same IP address.

Many modern [[operating system]]s notify the administrator of IP address conflicts.<ref>{{Cite web |date=26 August 2009 |title=Event ID 4198 — TCP/IP Network Interface Configuration |url=https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/dd379838(v=ws.10) |access-date=2023-09-03 |website=[[Microsoft Docs]] |department=[[Microsoft TechNet|TechNet]] |df=dmy-all}}</ref><ref>{{Cite web |date=26 August 2009 |title=Event ID 4199 — TCP/IP Network Interface Configuration |url=https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/dd379922(v=ws.10) |access-date=2023-09-03 |website=[[Microsoft Docs]] |department=[[Microsoft TechNet|TechNet]] |df=dmy-all}}</ref> When IP addresses are assigned by multiple people and systems with differing methods, any of them may be at fault.<ref>{{Cite web |last=Mitchell, Bradley |title=IP Address Conflicts – What Is an IP Address Conflict? |url=http://compnetworking.about.com/od/workingwithipaddresses/f/ip_conflict.htm |url-status=live |archive-url=https://web.archive.org/web/20140413194343/http://compnetworking.about.com/od/workingwithipaddresses/f/ip_conflict.htm |archive-date=13 April 2014 |access-date=23 November 2013 |publisher=[[About.com]] |df=dmy-all}}</ref><ref>{{Cite web |last=Kishore, Aseem |date=4 August 2009 |title=How to Fix an IP Address Conflict |url=https://www.online-tech-tips.com/computer-tips/ip-address-already-in-use/ |access-date=3 September 2023 |publisher=Online Tech Tips Online-tech-tips.com |df=dmy-all}}</ref><ref>{{Cite web |date=22 November 2013 |title=Get help with &quot;There is an IP address conflict&quot; message |url=http://windows.microsoft.com/en-us/windows7/get-help-with-there-is-an-ip-address-conflict-message |url-status=dead |archive-url=https://web.archive.org/web/20130926071157/http://windows.microsoft.com/en-us/windows7/get-help-with-there-is-an-ip-address-conflict-message |archive-date=26 September 2013 |access-date=23 November 2013 |publisher=[[Microsoft]] |df=dmy-all}}</ref><ref>{{Cite web |date=15 October 2013 |title=Fix duplicate IP address conflicts on a DHCP network |url=http://support.microsoft.com/kb/q133490 |url-status=live |archive-url=https://web.archive.org/web/20141228223206/http://support.microsoft.com/kb/q133490 |archive-date=28 December 2014 |access-date=23 November 2013 |publisher=[[Microsoft]] |df=dmy-all}}</ref><ref>{{Cite web |last=Moran, Joseph |date=1 September 2010 |title=Understanding And Resolving IP Address Conflicts |url=http://www.webopedia.com/DidYouKnow/Internet/2007/IP_Address_Conflicts.asp |url-status=live |archive-url=https://web.archive.org/web/20131002155215/http://www.webopedia.com/DidYouKnow/Internet/2007/IP_Address_Conflicts.asp |archive-date=2 October 2013 |access-date=23 November 2013 |publisher=Webopedia |df=dmy-all}}</ref> If one of the devices involved in the conflict is the [[default gateway]] access beyond the LAN for all devices on the LAN, all devices may be impaired.
