Configuring a Static IP Address for Dermi Atlas Professional

Why Static IP Matters

Configuring a static IP address is strongly recommended for the computer hosting Dermi Atlas Professional.

If the host IP address changes (due to DHCP reassignment):

• Access URLs will change, breaking bookmarks and PWA installations.
• HTTPS access can break temporarily. The certificate includes the host IP address, so when the IP changes, browsers will report a certificate mismatch until the certificate is regenerated and the new certificate is re-installed and trusted on every device. The Dermi Atlas Manager detects the new IP and regenerates the certificate on the next start, and the SSL Certificate card also offers a Refresh action for manual regeneration, but a static IP avoids this disruption entirely.
• Access will be lost until the new URL is applied.

Configuring Static IP via Router (Recommended)

The best method is to set a DHCP Reservation on the router. This assigns the same IP to the computer's MAC address every time it connects.

General Steps:

1. Find the MAC address:
   • Windows: Run ipconfig /all in Command Prompt.
   • macOS: System Settings => Network => Details => Hardware.
2. Log in to the router: Open a browser and enter the router's IP (e.g., 192.168.1.1).
3. Find DHCP Settings: Look for "DHCP Reservation," "Address Reservation," or "Static DHCP".
4. Add Reservation: Enter the computer's MAC address and the desired IP (e.g., 192.168.1.100).
5. Save and Restart: Save settings and restart the computer to apply the new IP.

Configuring Static IP on Host Computer

Alternatively, a static IP can be set directly in the OS network settings.

Windows

1. Go to Settings => Network & Internet.
2. Select Ethernet or Wi-Fi => Edit IP assignment.
3. Set to Manual. Enable IPv4.
4. Enter the desired IP, Subnet Mask (usually 255.255.255.0), Gateway (router IP), and DNS (router IP or 8.8.8.8).
5. Save.

macOS

1. Go to System Settings => Network.
2. Select connection => Details => TCP/IP.
3. Set Configure IPv4 to Manually.
4. Enter IP Address, Subnet Mask, and Router.
5. Click OK.

Ubuntu (GNOME)

1. Go to Settings => Network.
2. Click gear icon next to connection => IPv4.
3. Set Method to Manual.
4. Enter Address, Netmask, and Gateway.
5. Click Apply.

Verifying

After configuration, check Dermi Atlas Manager. The Atlas Access URLs should reflect the new static IP.

If the IP changed before a static address was configured, regenerate and re-trust the HTTPS certificate by following SSL Certificate Setup for HTTPS Access.
