ISC reports :
DNS protocols were designed with the assumption that a certain amount of trust could be presumed between the operators of primary and secondary servers for a given zone. However, in current practice some organizations have scenarios which require them to accept zone data from sources that are not fully trusted (for example: providers of secondary name service). A party who is allowed to feed data into a zone (e.g. by AXFR, IXFR, or Dynamic DNS updates) can overwhelm the server which is accepting data by intentionally or accidentally exhausting that server’s memory.
