Spectrum DNS Servers (71.10.216.1) & How to Change Them

What Are Spectrum DNS Servers?

Spectrum's DNS servers are 71.10.216.1 (primary) and 71.10.216.2 (secondary); over IPv6 they are 2607:f428:ffff:ffff::1 and 2607:f428:ffff:ffff::2. Spectrum names the IPv4 pair in its own DNS Upgrade Notification, and your router hands them to every device automatically.

They are run by Charter Communications, Spectrum's parent company, and only answer devices on Spectrum's network: from another ISP every lookup times out. Whether a public resolver is faster depends on where you are, so time Spectrum's against Cloudflare and Google from your own connection before you change anything.

Spectrum DNS Server IP Addresses (IPv4)

The current pair is the one Spectrum's support article names. The others are older Charter and Time Warner Cable resolvers: Spectrum's DNS Upgrade Notification says it has retired its old DNS servers in some areas, and asks anyone with manual DNS settings to switch to automatic, or to 71.10.216.1 and 71.10.216.2.

We checked all five on 26 October 2026: Charter's reverse DNS names every one, and every one times out from outside Spectrum's network. To see which pair your own connection uses, follow verify your DNS settings below.

Spectrum IPv6 DNS Servers

When your connection has IPv6, Spectrum hands out an IPv6 DNS pair too. It belongs to the same two servers as 71.10.216.1 and 71.10.216.2:

If you switch to another provider, change both IPv4 and IPv6 DNS: leaving IPv6 on Spectrum while changing only IPv4 sends some lookups to Spectrum anyway.

Cloudflare's IPv6 DNS servers are 2606:4700:4700::1111 and 2606:4700:4700::1001; Google's are 2001:4860:4860::8888 and 2001:4860:4860::8844.

Spectrum Business DNS Servers

Spectrum doesn't publish separate DNS servers for Spectrum Business: business connections get Spectrum's resolvers automatically, and you can see which pair yours uses with the nslookup check in verify your DNS settings. You can set any public resolver on your own router or devices instead.

For an office, a filtering resolver adds protection without extra software: Quad9 (9.9.9.9) blocks known malware and phishing domains, and Cloudflare for Families (1.1.1.3) and CleanBrowsing's Family filter also block adult content. If you host servers on a static IP, Spectrum Business support sets their reverse DNS (PTR) records; check them with DNS Robot's Reverse DNS tool.

Why Change Spectrum's Default DNS?

Spectrum's DNS works for everyday browsing. These are the reasons people switch:

• Speed, sometimes — a public resolver can be faster or slower than Spectrum's depending on your area: test both with the DNS Speed Test before you switch
• A fallback during outages — when Spectrum's resolvers fail, sites stop loading even though your connection works; a public resolver keeps names resolving
• Privacy — Spectrum's DNS Privacy Notice says it logs each lookup with your IP address and keeps that data for 72 hours as standard, longer for legal or security reasons; it doesn't sell it or use it for advertising. Cloudflare's 1.1.1.1 keeps no source IP on disk and deletes its logs within 25 hours, and an outside accounting firm audits that
• Security filtering — Quad9 (9.9.9.9) blocks known malicious domains, and Cloudflare for Families (1.1.1.3) blocks malware and adult content
• Encryption — Cloudflare, Google and Quad9 support DNS over HTTPS and DNS over TLS, so lookups can be encrypted between your device and the resolver

Best DNS Servers for Spectrum Users

These public resolvers are free and work on any Spectrum plan. Which is fastest depends on where you are, so the table compares what each one filters rather than a latency figure.

For most Spectrum users, Cloudflare (1.1.1.1) is the best overall pick for privacy, with audited logging commitments. For malware protection pick Quad9 (9.9.9.9); for family filtering, Cloudflare for Families (1.1.1.3) or OpenDNS FamilyShield.

Measure them from your own connection with DNS Robot's DNS Speed Test: it times these resolvers and your current Spectrum DNS from your browser and ranks them.

How to Change DNS on Your Spectrum Router

Changing DNS on your Spectrum router applies it to every device on your network: phones, laptops, smart TVs and consoles. Spectrum's routers are managed in the My Spectrum app; older models also have a web admin page.

Method 1: In the My Spectrum App

These are Spectrum's own steps for its Advanced WiFi routers:

• Step 1 — Open the My Spectrum app and sign in
• Step 2 — Tap the Services tab, then select your Router under Equipment
• Step 3 — Tap Advanced Settings, then DNS Server
• Step 4 — Tap Manage DNS, enter a primary and a secondary DNS server (for example 1.1.1.1 and 1.0.0.1), and tap Save
• Step 5 — To go back to Spectrum's DNS later, return to the same screen and choose Use Spectrum DNS

Method 2: On the Router's Admin Page (192.168.1.1)

Older Spectrum routers such as the RAC2V1K and RAC2V1A also have a web admin page:

• Step 1 — Go to 192.168.1.1 in a browser on your Spectrum network and sign in as admin (the RAC2V1K's guide gives the default password admin, unless you changed it)
• Step 2 — Click Advanced; it opens on the Internet tab
• Step 3 — Scroll to the DNS settings and set Connect to DNS Server to No, which makes the fields editable
• Step 4 — Enter your DNS servers, for example 1.1.1.1 and 1.0.0.1, and click Apply
• Step 5 — For IPv6, open the IPv6 settings, set Connect to DNS Server Automatically (labelled IPv6 DNS Settings on some firmware) to No, enter the IPv6 addresses and click Apply

Change DNS on Windows (Spectrum Connection)

If you can't change DNS on the router, you can change it per device. Here's how to do it on Windows 10 and 11.

Changing DNS on Windows needs administrator rights: run PowerShell or Command Prompt as Administrator for the commands below.

Windows 11 (Settings App)

The fastest way on Windows 11 is through the Settings app.

• Step 1 — Open Settings → Network & internet → Wi-Fi → Manage known networks → your network (for a cable: Ethernet → your network)
• Step 2 — Click Edit next to DNS server assignment
• Step 3 — Switch from Automatic (DHCP) to Manual
• Step 4 — Enable IPv4 and enter: Preferred DNS = 1.1.1.1, Alternate DNS = 1.0.0.1
• Step 5 — (Optional) Enable IPv6 and enter: 2606:4700:4700::1111 and 2606:4700:4700::1001
• Step 6 — Click Save

# PowerShell: Change DNS on active network adapter
$adapter = Get-NetAdapter | Where-Object {$_.Status -eq 'Up'} | Select-Object -First 1
Set-DnsClientServerAddress -InterfaceIndex $adapter.ifIndex -ServerAddresses '1.1.1.1','1.0.0.1','2606:4700:4700::1111','2606:4700:4700::1001'

# Verify the change
Get-DnsClientServerAddress -InterfaceIndex $adapter.ifIndex

Windows 10/11 (Command Prompt)

REM Find your network adapter name
netsh interface show interface

REM Set IPv4 DNS (replace "Wi-Fi" with your adapter name)
netsh interface ip set dns name="Wi-Fi" static 1.1.1.1
netsh interface ip add dns name="Wi-Fi" 1.0.0.1 index=2

REM Set IPv6 DNS too, so lookups don't split between providers
netsh interface ipv6 set dnsservers name="Wi-Fi" static 2606:4700:4700::1111
netsh interface ipv6 add dnsservers name="Wi-Fi" 2606:4700:4700::1001 index=2

REM Flush the DNS cache and check
ipconfig /flushdns
nslookup google.com

Change DNS on Mac (Spectrum Connection)

macOS makes it easy to change DNS servers through System Settings (macOS Ventura and later) or System Preferences (older versions).

• Step 1 — Open System Settings → Network → click your active connection (Wi-Fi or Ethernet)
• Step 2 — Click Details → select DNS from the sidebar
• Step 3 — Click the + button to add DNS servers. Enter 1.1.1.1 and 1.0.0.1
• Step 4 — Remove any existing Spectrum DNS entries by selecting them and clicking −
• Step 5 — Click OK

# Terminal: Set DNS for Wi-Fi interface
networksetup -setdnsservers Wi-Fi 1.1.1.1 1.0.0.1

# Flush DNS cache
sudo dscacheutil -flushcache && sudo killall -HUP mDNSResponder

# Verify DNS servers
networksetup -getdnsservers Wi-Fi

# Test DNS resolution
dig @1.1.1.1 google.com +short

Change DNS on iPhone & Android (Spectrum Wi-Fi)

If you're connected to Spectrum Wi-Fi but can't change the router settings, you can override DNS on your phone.

iPhone / iPad

• Step 1 — Open Settings → Wi-Fi → tap the (i) icon next to your Spectrum network
• Step 2 — Scroll down and tap Configure DNS
• Step 3 — Switch from Automatic to Manual
• Step 4 — Delete existing DNS entries, then tap Add Server and enter 1.1.1.1 and 1.0.0.1
• Step 5 — Tap Save

Android

Android 9+ has a built-in Private DNS feature that applies encrypted DNS globally — across all networks, including Spectrum Wi-Fi and mobile data.

• Step 1 — Open Settings → Network & Internet → Private DNS (on Samsung: Connections → More connection settings → Private DNS)
• Step 2 — Select Private DNS provider hostname
• Step 3 — Enter one.one.one.one (Cloudflare) or dns.google (Google DNS)
• Step 4 — Tap Save

How to Verify Your DNS Settings Changed

After changing DNS, check that your device really uses the new servers.

# Windows, Mac or Linux: which DNS server does this device ask?
nslookup google.com
# The "Server:" line shows it: 1.1.1.1 after a device change.
# After a router change it may show the router (192.168.1.1): the DNS Leak Test shows the real resolver

# Mac/Linux: compare response times
dig google.com @1.1.1.1 | grep "Query time"
dig google.com @71.10.216.1 | grep "Query time"

DNS Robot's DNS Leak Test shows the resolvers your device really uses, with their names and networks, so you can confirm the switch from your browser.

If you still see Spectrum's DNS (71.10.216.1), flush your DNS cache and restart your browser. A router-level change reaches each device when it reconnects: turn its Wi-Fi off and on.

Common Spectrum DNS Issues & Fixes

When Spectrum's DNS fails, sites stop loading even though the modem shows a working connection. Here are the common problems and their fixes.

DNS Server Not Responding on Spectrum

Your browser shows "DNS server not responding" or DNS_PROBE_FINISHED_NXDOMAIN while the modem shows a solid connection. First find out whether Spectrum's DNS is the problem: ask Spectrum's server and a public one for the same name.

# Ask Spectrum's resolver, then Cloudflare's, for the same name
nslookup example.com 71.10.216.1
nslookup example.com 1.1.1.1

# Spectrum fails, Cloudflare answers  → Spectrum's DNS is the problem: switch DNS
# Both fail                           → your connection is down: restart the modem and router

Then fix it in this order:

• Switch DNS — set Cloudflare (1.1.1.1) or Google (8.8.8.8) on your device or router to bypass Spectrum's resolvers
• Restart the modem and router — unplug both for 30 seconds, plug in the modem first, wait 2 minutes, then plug in the router
• Flush the DNS cache — ipconfig /flushdns on Windows or sudo dscacheutil -flushcache on Mac (all systems)
• Check for an outage — the My Spectrum app, or Downdetector Spectrum. For more, see how to fix DNS server not responding

Slow DNS Lookups on Spectrum

If websites pause before they start loading but then download quickly, slow DNS is a likely cause: each new site name waits for the resolver, and a single page can need dozens of them.

Measure before you switch: DNS Robot's DNS Speed Test times Cloudflare, Google, Quad9 and others against your current Spectrum DNS from your own connection and ranks them. Pick the fastest one for your area; the Ping tool compares raw latency to each resolver.

Spectrum Router Locks DNS Settings

If the DNS fields are greyed out, revert after saving, or your router has no DNS setting at all, you can still change DNS:

• Use your own router — connect your own Wi-Fi router (TP-Link, Netgear, ASUS and others) to Spectrum's modem for full control over DNS and every other setting
• Change DNS per device — Set DNS on each computer, phone, and tablet individually instead of on the router
• Use Private DNS (Android) — Android's built-in Private DNS overrides the router's DNS at the OS level
• Use DoH in your browser — Chrome, Firefox and Edge support DNS over HTTPS, which sends the browser's lookups to the resolver you pick instead of the router's
