Nslookup löst nur ipv4 auf

florian2833z · 6. Februar 2018

Hallo,

Wenn ich unter Linux nslookup verwende, löst er mir statt A und AAAA nur A auf.

Code

root@marie:~# nslookup google.com
Server:         9.9.9.10
Address:        9.9.9.10#53

Non-authoritative answer:
Name:   google.com
Address: 216.58.205.46

root@marie:~#

Zudem benutzt er immer einen IPv4 DNS server ...

Code

root@marie:~# nslookup ipv6.google.com
Server:         9.9.9.10
Address:        9.9.9.10#53

Non-authoritative answer:
ipv6.google.com canonical name = ipv6.l.google.com.

Meine resolv.conf sieht so aus:

Code

root@marie:~# cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 9.9.9.10
nameserver 2620:fe::fe
nameserver 8.8.8.8
root@marie:~#

Mit dig kann ich problemlos IPv6 Adressen auflösen ...

Code

root@marie:~# dig -6 ipv6.google.com

; <<>> DiG 9.10.3-P4-Debian <<>> -6 ipv6.google.com

Du denkst vermutlich an host(1)

Code

user@host:~# host google.com
google.com has address 172.217.18.14
google.com has IPv6 address 2a00:1450:400e:805::200e
google.com mail is handled by 10 aspmx.l.google.com.
google.com mail is handled by 50 alt4.aspmx.l.google.com.
google.com mail is handled by 20 alt1.aspmx.l.google.com.
google.com mail is handled by 30 alt2.aspmx.l.google.com.
google.com mail is handled by 40 alt3.aspmx.l.google.com.
