Hello,

Using BIND 9.5.1 it seems that the nslookup command is not showing the
TTL value of found records. It makes no difference if I set 'debug' or
'd2'. Example:

==============================================================
nslookup
> set debug
> www.plymouth.ac.uk
Server:         127.0.0.1
Address:        127.0.0.1#53

------------
    QUESTIONS:
        www.plymouth.ac.uk, type = A, class = IN
    ANSWERS:
    ->  www.plymouth.ac.uk
        canonical name = extranet.plymouth.ac.uk.
    ->  extranet.plymouth.ac.uk
        internet address = 141.163.163.185
    AUTHORITY RECORDS:
    ->  plymouth.ac.uk
        nameserver = dns0.plymouth.ac.uk.
    ->  plymouth.ac.uk
        nameserver = dns1.plymouth.ac.uk.
    ADDITIONAL RECORDS:
    ->  dns0.plymouth.ac.uk
        internet address = 141.163.1.250
    ->  dns1.plymouth.ac.uk
        internet address = 141.163.177.1
------------
www.plymouth.ac.uk      canonical name = extranet.plymouth.ac.uk.
Name:   extranet.plymouth.ac.uk
Address: 141.163.163.185
>
==============================================================


How can I see the TTL value using nslookup?



Thanks,

John.
