Great point. But note that the problem is not specific to OpenDNS alone. Any hosted DNS service has exactly the same problem. Perhaps the best option is to run bind as a caching name server for local users. IIRC, the default config of every distro is to run bind as a pure cache only name server. However, OpenDNS/GoogleDNS/etc have some neat technology deployed through UDP Anycast. Good reading for any networking enthusiast. And in any case, these services are far better than the DNS infrastructure provided by Indian ISPs. But since the OP has problems with Skype disconnects, his issue is not with DNS at all. Skype super node IPs are 1) hard coded in the binary, 2) updated on every connect, and 3) cached locally. Skype works perfectly even when DNS is not configured in your box. Perhaps OP should consider checking the physical DSL/telephone cable or the issue could also be due to congestion in the BSNL network. - Raja _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
