Proactive caching of DNS records: addressing a performance bottleneck

Edith Cohen, Haim Kaplan
2003 Computer Networks  
A DNS query is issued if the respective cached entry is no longer fresh, but concurrently, the expired entry is used to connect to the Web server and fetch the requested content.  ...  The resolution of a host name to an IP-address is a nec essary predecessor to connection establishment and HTTP exchanges.  ...  The perhaps smaller-than-expected advantage of R-ADAPTIVE is explained by a large number of hosts with a small number of "misses" on the learning data.  ...
