Baidu DNS Infrastructure
bdydns.com is a DNS infrastructure domain operated by Baidu, China's largest search engine and internet services company. The domain name derives from "Baidu DNS" (ηΎεΊ¦DNS) and serves as the authoritative nameserver infrastructure for Baidu's services and potentially for domains using Baidu's DNS hosting.
DNS Infrastructure
The domain operates six nameservers distributed across major Chinese network providers for redundancy and performance:
- China Telecom (ns1): 14.215.178.30
- China 169-Backbone (ns2): 112.80.255.17
- CMNET/China Mobile Guangdong (ns3, ns5): 183.232.232.21
- ChinaNet Nanjing (ns4): 180.97.33.33 (also IPv6: 240e:bf:b801:1771:0:ff:b05b:3e70)
- Baidu Direct (ns6): 180.76.76.15
This multi-provider distribution ensures high availability and low latency across China's diverse network infrastructure.
Notable Facts
- Tranco Rank: #680 (30-day), indicating significant DNS query volume
- DNSSEC: Not enabled (no DS record)
- The domain itself has no A record (not designed to host web content)
- Part of Baidu's broader cloud and infrastructure services ecosystem
