Finding Subnet Mask & Gateway for Xbox Live: Check Router / PC, Not Xbox

Xbox Live doesn't assign these. They are your home network settings (Router/ISP).

Find on Windows PC (Same Network)

1. Win+R → cmd → Enter.
2. Type ipconfig → Enter.
3. Find your active adapter (Wi-Fi / Ethernet).
4. IPv4 Address: Your PC's IP (e.g., 192.168.1.50).
5. Subnet Mask: Usually 255.255.255.0 (/24).
6. Default Gateway: Your Router IP (e.g., 192.168.1.1 or 192.168.0.1).

Find on Router Admin Page

1. Browser → https://192.168.1.1 or https://192.168.0.1 (or Gateway IP from above).
2. Login (admin/password on sticker).
3. LAN / DHCP Settings → See Subnet Mask, Gateway, DHCP Range.

Xbox Network Settings (Static IP Setup)

If setting Static IP on Xbox 360/One/Series:

• IP: Gateway IP + high number (e.g., 192.168.1.200) – outside DHCP pool.
• Subnet Mask: Copy from PC/Router (usually 255.255.255.0).
• Gateway: Copy Router IP.
• DNS: 1.1.1.1 / 1.0.0.1 (Cloudflare) or 8.8.8.8 / 8.8.4.4 (Google) or Router IP.

These settings fix NAT Type / Port Forwarding issues.
