1.1.1 display dns ipv6 dynamic-host
Syntax
display dns ipv6 dynamic-host
View
Any view
Parameters
None
Description
Use the display dns ipv6 dynamic-host command to display IPv6 dynamic domain
name information in the cache, including the domain name, IPv6 address, and TTL of
the DNS entries.
You can use the reset dns ipv6 dynamic-host command to clear all IPv6 dynamic
domain name information from the cache.
Examples
# Display IPv6 dynamic domain name information in the cache.
<Sysname> display dns ipv6 dynamic-host
No. Domain-name IPv6 Address TTL
1 aaa 2001::2 6
Table 1-1 Description on the fields of the display dns ipv6 dynamic-host command
Field Description
No. Sequence number
Domain-name Domain name
IPv6 Address IPv6 address of the corresponding domain name
TTL Time-to-live of the domain name in the cache in seconds

Note:
When you use the display dns ipv6 dynamic-host command to check the IPv6
dynamic domain names in the cache, the system will display the first 21 characters of
the domain names if they contain more than 21 characters. This is because the domain
name displayed in the Domain-name field can be up to 21 characters in length.

Use the display tcp ipv6 statistics command to display statistics of IPv6 TCP
packets.
You can use the reset tcp ipv6 statistics command to clear statistics of all IPv6 TCP
packets.
