Global Anycast Network
Understanding Global Anycast Network
Anycast is a network addressing and routing methodology that attributes a single IP address to multiple DNS servers in a network.
The basis of Anycast is that the user's location is used to determine which one of the name servers is the nearest to transmit the data to.
This strategy, reduces the time taken for data transfer because it passes through the least number of network servers — promoting an efficient and repeatable world-wide web experience for all users.
Anycast Key Points
- Speedier Connectivity
- Data is channelled to the closest DNS server, minimising outward and return journey time.
- Load Balanced
- Every DNS server is able to respond and process data requests and by using IP Addresses (instead of DNS) failover is achieved.
- Clear Configuration Administration
- Each DNS server is delivered the same server configuration.
- DDoS Reduction
- After screening, the DDoS attack traffic is dispersed throughout many data centres; in this way, no single server is suffocated with requests.
