★.1host：DNS信息

参数：

一般情况下，host查找的是A，AAAA，和MX的记录

案例：

DNS服务器查询

host -t ns 域名

A记录和MX记录查询

host 域名（host -t a 域名 + host -t mx 域名）

PS：A (Address) 记录是用来指定主机名（或域名）对应的IP地址记录。用户可以将该域名下的网站服务器指向到自己的web server上。同时也可以设置您域名的子域名。通俗来说A记录就是服务器的IP,域名绑定A记录就是告诉DNS,当你输入域名的时候给你引导向设置在DNS的A记录所对应的服务器。 PS：MX记录也叫做邮件路由记录，用户可以将该域名下的邮件服务器指向到自己的mail server上，然后即可自行操控所有的邮箱设置。您只需在线填写您服务器的IP地址，即可将您域名下的邮件全部转到您自己设定相应的邮件服务器上。简单的说，通过操作MX记录，您才可以得到以您域名结尾的邮局。

4.2Dig ：DNS挖掘

参数： root@Kali:/home/dnt# dig -h Usage: dig [@global-server] [domain] [q-type] [q-class] {q-opt} {global-d-opt} host [@local-server] {local-d-opt} [ host [@local-server] {local-d-opt} [...]] Where: domain is in the Domain Name System q-class is one of (in,hs,ch,...) [default: in] q-type is one of (a,any,mx,ns,soa,hinfo,axfr,txt,...) [default:a] (Use ixfr=version for type ixfr) q-opt is one of: -x dot-notation (shortcut for reverse lookups) -i (use IP6.INT for IPv6 reverse lookups) -f filename (batch mode) -b address[#port] (bind to source address/port) -p port (specify port number) -q name (specify query name) -t type (specify query type) -c class (specify query class) -k keyfile (specify tsig key file) -y [hmac:]name:key (specify named base64 tsig key) -4 (use IPv4 query transport only) -6 (use IPv6 query transport only) -m (enable memory usage debugging) d-opt is of the form +keyword[=value], where keyword is: +[no]vc (TCP mode) +[no]tcp (TCP mode, alternate syntax) +time=### (Set query timeout) [5] +tries=### (Set number of UDP attempts) [3] +retry=### (Set number of UDP retries) [2] +domain=### (Set default domainname) +bufsize=### (Set EDNS0 Max UDP packet size) +ndots=### (Set NDOTS value) +[no]edns[=###] (Set EDNS version) [0] +[no]search (Set whether to use searchlist) +[no]showsearch (Search with intermediate results) +[no]defname (Ditto) +[no]recurse (Recursive mode) +[no]ignore (Don't revert to TCP for TC responses.) +[no]fail (Don't try next server on SERVFAIL) +[no]besteffort (Try to parse even illegal messages) +[no]aaonly (Set AA flag in query (+[no]aaflag)) +[no]adflag (Set AD flag in query) +[no]cdflag (Set CD flag in query) +[no]cl (Control display of class in records) +[no]cmd (Control display of command line) +[no]comments (Control display of comment lines) +[no]rrcomments (Control display of per-record comments) +[no]question (Control display of question) +[no]answer (Control display of answer) +[no]authority (Control display of authority) +[no]additional (Control display of additional) +[no]stats (Control display of statistics) +[no]short (Disable everything except short form of answer) +[no]ttlid (Control display of ttls in records) +[no]all (Set or clear all display flags) +[no]qr (Print question before sending) +[no]nssearch (Search all authoritative nameservers) +[no]identify (ID responders in short answers) +[no]trace (Trace delegation down from root [+dnssec]) +[no]dnssec (Request DNSSEC records) +[no]nsid (Request Name Server ID) +[no]sigchase (Chase DNSSEC signatures) +trusted-key=#### (Trusted Key when chasing DNSSEC sigs) +[no]topdown (Do DNSSEC validation top down mode) +[no]split=## (Split hex/base64 fields into chunks) +[no]multiline (Print records in an expanded format) +[no]onesoa (AXFR prints only one soa record) +[no]keepopen (Keep the TCP socket open between queries) global d-opts and servers (before host name) affect all queries. local d-opts and servers (after host name) affect only that lookup. -h (print help and exit) -v (print version and exit)
常用：dig 域名 any

root@Kali:/home/dnt# dig cnblogs.com any ; <<>> DiG 9.9.5-9+deb8u2-Debian <<>> cnblogs.com any ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 18664 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;cnblogs.com.
