The question "What is Google DNS hostname?" is somewhat misleading because Google Public DNS does not use hostnames in the traditional sense for its primary service. Instead, it uses IP addresses. However, we can discuss what the Google Public DNS service is and its associated IPs and implied hostnames.
Understanding Google Public DNS
Google Public DNS is a free, global Domain Name System (DNS) service that you can configure on your devices or network to improve internet speed and reliability. Instead of relying on your Internet Service Provider's (ISP) DNS servers, you can use Google's.
Google Public DNS IP Addresses
The primary identifiers for Google Public DNS are its IP addresses. According to the reference, the main IPv4 addresses are:
| IP Address | Type |
|---|---|
| 8.8.8.8 | IPv4 |
| 8.8.4.4 | IPv4 |
These are the addresses you would enter into your device or router’s network settings to use Google Public DNS.
Implied Hostnames (Not Directly Used)
While not directly used as traditional hostnames, these IP addresses are often associated with the implied hostnames:
- google-public-dns-a.google.com (associated with 8.8.8.8)
- google-public-dns-b.google.com (associated with 8.8.4.4)
These implied hostnames are used for management, monitoring, and reverse DNS lookups but are not typically used by end-users for configuration.
How to Use Google Public DNS
To use Google Public DNS, you would:
- Locate your device's network settings: This varies by device.
- Find the DNS settings: Look for options related to DNS or nameservers.
- Enter the IP addresses: Replace your existing DNS servers with
8.8.8.8and8.8.4.4.
Advantages of Using Google Public DNS:
- Faster Lookups: Google's DNS servers are often faster than those of your ISP.
- Increased Reliability: Google's robust infrastructure provides greater uptime.
- Security Features: May include DNSSEC validation for added security.
In summary, while there isn't a hostname that you use to directly configure Google Public DNS, the service is accessible via IP addresses 8.8.8.8 and 8.8.4.4. Associated hostnames like google-public-dns-a.google.com and google-public-dns-b.google.com are used internally but not for direct configuration.
