They work well. That's why, majority of content providers are using them.

I search a lot for but didn't find answer for my question. I have few questions about there working model. First is, why they are doing CNAME 4 time for each zone?? For ex: ;; QUESTION SECTION: ;www.cisco.com. IN A ;; ANSWER SECTION: www.cisco.com. 236 IN CNAME www.cisco.com.akadns.net. www.cisco.com.akadns.net. 268 IN CNAME geoprod.cisco.com.akadns.net. geoprod.cisco.com.akadns.net. 206 INCNAME www.cisco.com.edgekey.net. www.cisco.com.edgekey.net. 11010 IN CNAME www.cisco.com.edgekey.net.globalredir.akadns.net. www.cisco.com.edgekey.net.globalredir.akadns.net. 257 IN CNAME e144.cd.akamaiedge.net. e144.cd.akamaiedge.net. 7 IN A 125.252.232.170 What's the need of doing CNAME 4 times and AKAMAI does this thing for each domain they takes care of.

I know, they've helped me answer stupid questions on many occasions. It's almost rude to ask about their architecture on a somewhat unrelated public forum. http://www.akamai.com/dl/technical_publications/GloballyDistributedContentDe livery.pdf On a more generic note, the CNAME trick is often employed by people building GSLB architectures. We do the same for our internal implementation. It is usually administrative trickery (or creative thinking) to increase efficiency, e.g. Delegate a globally load balanced sub-domain to a set of GSLB devices (thousands in their case, our own implementation is not yet nearly as robust) and then CNAME as needed vs. delegating everything. -- Work is the curse of the drinking classes. -- Mike Romanoff ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
