If Xbox ignores the DNS addresses you entered, your router may still be advertising a separate IPv6 DNS server. You only need to try this if the normal Xbox setup does not work.

1. On Xbox, open Settings → General → Network settings → Advanced settings. Check whether the console shows IPv6 connectivity. Keep your Aster IPv4 DNS addresses recorded.
2. On a phone or PC connected to the same home network, open your router's administration page (often the Default Gateway address shown in your network settings). Sign in using the router administrator credentials, not your Aster or Microsoft password.
3. Find the IPv6 or LAN settings. Look for IPv6 DNS, DHCPv6 DNS, or Router Advertisement (RA/RDNSS) DNS. On some routers these are under Home Network → Network → IPv6, LAN → DHCPv6, or Internet → IPv6.
4. If the router supports specifying IPv6 DNS servers, use only IPv6 DNS addresses explicitly provided by your trusted DNS service. Do not enter IPv4 addresses into IPv6 fields or invent an IPv6 address from your IPv4 DNS. Aster's listed IPv4 DNS addresses are not interchangeable with IPv6 DNS.
5. If there is no suitable IPv6 DNS option, do not blindly disable IPv6 or change unrelated WAN settings. Some routers or internet providers do not offer control over advertised IPv6 DNS. Ask the network administrator or your ISP about the supported options.
6. Save changes only if you understand their effect, reconnect the Xbox to the network, then use Test network connection. If it still fails, restore the previous settings and contact Aster support with the router model and error shown.

Important: Changing DNS on your router can affect every device in your home. Get permission from the network owner and record original settings first. Using NextDNS on the whole router can also send household DNS requests to that service and count toward its query allowance. Changing DNS does not bypass HTTPS certificate validation or guarantee that the game connects.

Do not change your household router to NextDNS for Aster. That can send everyone’s DNS lookups to the provider. Manual console DNS can still be bypassed by automatically supplied IPv6 DNS, so this setup is not guaranteed on all networks.

Yes. NextDNS counts all DNS queries sent to it, including Roblox, YouTube and other websites. Only the listed game hostnames are redirected; other names resolve normally but still count. Separate profiles share the host’s account allowance. An independent DNS gateway would need separate hosting to avoid that quota.

Set DNS to Automatic on your device. Restore any router setting you changed. Close and reopen the game.
