Fix Local DNS — Complete Guide

Last Updated: 2026-01-31
Document Version: 1.0
Status: Active Documentation

Issue: DNS_PROBE_FINISHED_NXDOMAIN for explorer.d-bis.org, explorer.defi-oracle.io, and all endpoints.

Cause: Your device/network DNS (ISP, router, or cached) is not resolving these domains. Cloudflare and Google DNS resolve them correctly.

Quick Fix (Run This)

sudo ./scripts/fix-local-dns-hosts.sh

This will:

Add 21 domain entries to /etc/hosts → 76.53.10.36
(WSL) Set /etc/resolv.conf to use Cloudflare DNS (1.1.1.1, 1.0.0.1)
(WSL) Add generateResolvConf = false to /etc/wsl.conf so DNS persists

Note: If you can't use sudo, run without it to see the hosts entries — then add them manually with sudo nano /etc/hosts.

Domains Added

Domain	Purpose
explorer.d-bis.org	Blockscout explorer
explorer.defi-oracle.io	Explorer (alias)
rpc-http-pub.d-bis.org	RPC HTTP
rpc-ws-pub.d-bis.org	RPC WebSocket
rpc.d-bis.org, rpc2.d-bis.org	RPC aliases
ws.rpc.d-bis.org, ws.rpc2.d-bis.org	WebSocket aliases
rpc-http-prv.d-bis.org, rpc-ws-prv.d-bis.org	Private RPC
dbis-admin.d-bis.org, dbis-api.d-bis.org, etc.	DBIS services
mim4u.org, secure.mim4u.org, training.mim4u.org	MIM4U sites
rpc.public-0138.defi-oracle.io, rpc.defi-oracle.io, wss.defi-oracle.io	Defi Oracle RPC

Verify

# Should return 76.53.10.36
getent hosts explorer.d-bis.org

# Should return HTTP 200
curl -sI https://explorer.d-bis.org/ | head -3

Alternative: Force Cloudflare DNS (No hosts file)

WSL — Create /etc/wsl.conf:

[network]
generateResolvConf = false

Then set /etc/resolv.conf:

nameserver 1.1.1.1
nameserver 1.0.0.1

Restart WSL: wsl --shutdown (from PowerShell), then reopen your terminal.

Other Devices (Mobile, Windows, Mac)

Windows: Settings → Network → DNS → Manual → 1.1.1.1, 1.0.0.1
Mac: System Settings → Wi-Fi → Details → DNS → Add 1.1.1.1
iPhone: Settings → Wi-Fi → (i) → Configure DNS → Manual → 1.1.1.1
Android: Settings → Private DNS → dns.cloudflare.com
