The TTL ("Time To Live") setting tells DNS clients how long they may cache the results of their DNS queries - if you set the value too low (for example, to "1" for one second) the load on your DNS server will increase dramatically once the original TTL has expired (i.e. if your TTL is set to "3600" but you change it to "1", you will probably see an increase in DNS queries after an hour).
