This automated resolution updates services managed by the Server app. When you click the button, the Server app runs the changeip command-line tool. The alert contains a button you can click to update services to use the new network configuration. For more information, search Mac Help for “Join your Mac to a network account server.”Īfter you change the server’s IP address, an alert about it appears in the Server app’s Alerts pane. It will show IP addresses and MAC addresses, and is useful for troubleshooting and other. If this happens, users need to remove your server from their list of network account servers and then add it back. There's a Terminal command called arp that lets you find network devices on your local area network (LAN). If your server provides its own DNS service, you can use the Server app to update it.Ĭhanging your server’s IP address may disrupt the connections of users’ computers that have macOS installed. If your DNS service is provided by your ISP or another server on your network, ask your ISP or the DNS server administrator to update your server’s DNS records. Also, a reverse lookup of the new IP address must point to your server’s host name. If the IP address can’t be edited, change the Configure IPv4 setting to Manually or “Using DHCP with manual address.”Īfter you change your server’s IP address, the DNS server for your network must be updated so that your server’s host name points to the new IP address. If you have an internet router, it’s probably your DHCP server, and you should see its documentation for instructions. This feature is called static mapping or DHCP reservations. The DHCP server should be configured to assign your server the same IP address all the time. In this case, the DHCP server for your network assigns an IP address to your server. You can’t change the IP address if the Configure IPv4 setting is Using DHCP. Select the network service listed on the left (for example, Ethernet 1), then enter an IP address on the right. Select how users will access your server, then click Next.

Select the server in the Server app sidebar, click Overview, then click your server.Ĭlick Edit next to Edit Host Name, then click Next.
