DNS zone transfer, also sometimes known by the inducing DNS query type AXFR, is a type of DNS transaction. It is one of the many mechanisms available for administrators to replicate DNS databases across a set of DNS servers. Zone transfer comes in two flavors, full (AXFR) and incremental (IXFR). \newline % Row Count 7 (+ 6)
{\bf{Cache Snooping}} \newline % Row Count 8 (+ 1)
DNS cache snooping is when someone queries a DNS server in order to find out (snoop) if the DNS server has a specific DNS record cached, and thereby deduce if the DNS server's owner (or its users) have recently visited a specific site. \newline % Row Count 13 (+ 5)
This may reveal information about the DNS server's owner, such as what vendor, bank, service provider, etc. they use. Especially if this is confirmed (snooped) multiple times over a period. This method could even be used to gather statistical information - for example at what time does the DNS server's owner typically access his net bank etc. The cached DNS record's remaining TTL value can provide very accurate data for this. Great for determining relations and outside services used that can be leveraged in Phising attempts% Row Count 24 (+ 11)

It provides original and definitive answers to DNS queries. It does not provides just cached answers that were obtained from another name server. Therefore it only returns answers to queries about domain names that are installed in its configuration system. There are two types of Authoritative Name Servers: \newline % Row Count 10 (+ 10)
- {\bf{Master server (primary name server):}} A master server stores the original master copies of all zone records. A hostmaster only make changes to master server zone records. Each slave server gets updates via special automatic updating mechanism of the DNS protocol. All slave servers maintain an identical copy of the master records \newline % Row Count 17 (+ 7)
- {\bf{Slave server (secondary name server):}} A slave server is exact replica of master server. It is used to share DNS server load and to improve DNS zone availability in case master server fails.

{\bf{Recursive:}} A recursive nameserver is one that answers queries by asking other nameservers for the answer.  It will satisfy queries from cache if possible, but otherwise it traverses the Internet (or private) namespace tree, from the root level if necessary, repeatedly asking the query on behalf of its client and following referrals from authoritative servers until it finds one that provides the answer(s) that it can return to its client \newline % Row Count 33 (+ 9)

DNS caches improve the efficiency of the DNS by reducing DNS traffic across the Internet, and by reducing load on authoritative name-servers, particularly root name-servers. Because they can answer questions more quickly, they also increase the performance of end-user applications that use the DNS. Recursive name servers resolve any query they receive, even if they are not authoritative for the question being asked, by consulting the server or servers that are authoritative for the question.
