Verwendung
nslookup wird dazu verwendet um Domains (lookup) und IP-Adressen (reverse lookup) aufzulösen
A-Record herausfinden
Ein A-Record ordnet einen Domänennamen der IP-Adresse (IPv4) des Rechners zu, auf dem die Domäne gehostet wird.
root@foxriver:~# nslookup xinux.de
Server: 10.80.0.2 Address: 10.80.0.2#53 Non-authoritative answer: Name: xinux.de Address: 94.130.248.212
NS-Record
Ein NS-Record wird verwendet, um eine Subdomäne an eine Reihe von Nameservern zu delegieren.
root@foxriver:~# nslookup -type=ns xinux.de
Server: 10.80.0.2 Address: 10.80.0.2#53 Non-authoritative answer: xinux.de nameserver = gaius.tuxmen.de. xinux.de nameserver = nagus.tuxmen.de. Authoritative answers can be found from: gaius.tuxmen.de internet address = 78.47.133.194 nagus.tuxmen.de internet address = 24.134.2.5
SOA-Record
Start of Authority
root@foxriver:~# nslookup -type=soa xinux.de
Server: 10.80.0.2
Address: 10.80.0.2#53
Non-authoritative answer:
xinux.de
origin = gaius.tuxmen.de
mail addr = technik.xinux.de
serial = 2018090601
refresh = 14400
retry = 1800
expire = 604800
minimum = 86400
Authoritative answers can be found from:
xinux.de nameserver = gaius.tuxmen.de.
xinux.de nameserver = nagus.tuxmen.de.
gaius.tuxmen.de internet address = 78.47.133.194
nagus.tuxmen.de internet address = 24.134.2.5
MX-Record
E-Mail exchange
root@foxriver:~# nslookup -query=mx xinux.de
Server: 10.80.0.2 Address: 10.80.0.2#53 Non-authoritative answer: xinux.de mail exchanger = 10 thor.tuxmen.de. xinux.de mail exchanger = 20 gaius.tuxmen.de. Authoritative answers can be found from: xinux.de nameserver = nagus.tuxmen.de. xinux.de nameserver = gaius.tuxmen.de. thor.tuxmen.de internet address = 94.130.248.212 gaius.tuxmen.de internet address = 78.47.133.194 nagus.tuxmen.de internet address = 24.134.2.5
