Bug description:dns_get_record() - garbage in 'ipv6' field
Description:
------------
When calling dns_get_record($host, DNS_AAAA) for a single specific hostname
("snowflake.nullroute.eu.org"), random garbage is appended to the 'ipv6'
field of the DNS response.
The DNS response itself is valid (tested using Wireshark).
<tshark-output filter="udp port 53">
192.168.1.94 -> 8.8.8.8 DNS Standard query AAAA
snowflake.nullroute.eu.org
8.8.8.8 -> 192.168.1.94 DNS Standard query response AAAA
2001:470:1f0b:614:2ff:76ff:fe90:0
