Introducing the IPv6 Compatibility Checker Tool
The IPv6 Compatibility Checker tool assesses whether a domain utilizes IPv6 within its network
infrastructure. By querying the domain's DNS records, this tool verifies if the IPv6 DNS Records
resolve correctly, ensuring they return valid values. Simply enter a domain name, and this tool
swiftly evaluates its IPv6 compatibility.
Key Points on IPv6 Deployment
The implementation of Internet Protocol Version 6 (IPv6)
has been underway since the mid-2000s, aiming to replace IPv4, which has been in use since 1982
and is nearing exhaustion of its address space. However, IPv4 remains the dominant and most
familiar IP
protocol.
Several noteworthy observations have emerged regarding IPv6 adoption:
- More than 25% of all Internet-connected networks now support IPv6 connectivity.
- According to Google statistics, 49 countries exhibit over 5% of their traffic over IPv6
networks, with 24 countries surpassing 15%.
- IPv6 support is evident in 17% of Alexa Top Million Websites and 28% of Alexa Top 1000
Websites.
- As of November 2016, 98.4% of TLDs supported IPv6 for accessing their domain nameservers,
with nearly all popular DNS servers now supporting IPv6.
- ICANN mandates that all new TLDs must be IPv6-capable from launch, and data indicates over
11 million registered domains with AAAA records.
- Among 54,154 Autonomous Systems, approximately 25.8% advertise an IPv6 prefix, with Facebook
and Microsoft notably advancing IPv6 adoption.
- IPv6 has transitioned from early adoption to early majority phase, with cloud hosting
providers increasingly charging for IPv4 addresses while offering IPv6 services at no
additional cost.
Note: Data is based on 2017 statistics.
Exploring the IPv6 Compatibility Checker Tool
This tool validates IPv6 DNS records to confirm a domain's compatibility and support for IPv6
within its network. AAAA DNS Records contain the IPv6 address of a domain, facilitating
communication between IPv6 users and the website's server. Ensuring proper setup of AAAA DNS
Records is crucial for website owners to avoid broken connections with IPv6 users.
As of November 2024, approximately 25.9% of all websites support IPv6.  Among the top 1,000 global
websites, nearly half have deployed IPv6. 
Notable websites that support IPv6 include:
- Google: The search engine giant has been a leader in IPv6 adoption,
ensuring its services are accessible over IPv6.
- YouTube: As a subsidiary of Google, YouTube also supports IPv6, allowing
users to stream videos over the newer protocol.
- Facebook: The social media platform has enabled IPv6 across its services to
accommodate the growing number of IPv6 users.
- Wikipedia: The free online encyclopedia supports IPv6, ensuring
accessibility to a broader audience.
- Yahoo: This web services provider has implemented IPv6 to enhance user
experience and connectivity.
- Instagram: The photo and video sharing platform supports IPv6, aligning
with its parent company Facebook’s adoption.
- LinkedIn: The professional networking site has enabled IPv6 to support its
global user base.
- Netflix: The streaming service utilizes IPv6 to deliver content efficiently
to its subscribers.
- Apple: The tech giant has integrated IPv6 support across its services and
platforms.
- Microsoft: With services like Office.com, Microsoft has embraced IPv6 to
improve connectivity and performance.
- Twitter: The microblogging platform supports IPv6, enabling users to access
its services over the newer protocol.
