    Hello,

    I have Mac OS X Leopard 10.5.6 up to date and since few days, the DNS resolution is very slow, about 5 seconds to resolve names.


    For example :
    # ping test.com
    (wait 5 seconds)
    PING test.com (205.178.152.103): 56 data bytes

    Of course it also happen in firefox and in all other internet applications. Each time I'm loading a web page, I have to wait 5 seconds...
    If I try a few seconds later, it answer immediately, but a few minutes later, it take again 5 seconds to resolve the name.
    I'm not sure, and maybe it's just a coincidence, but it came just after the installation of Adobe Photoshop 4.
    I think about a virus or some mysterious mac os parameters ...

    I try dscacheutil -flushcache with no effect.

    My /etc/hosts is :
    nameserver 212.27.40.240

    I only have 1 dns server, and when I try :

    nslookup test.com 212.27.40.240

    It answer immediately :

    Server: 212.27.40.240
    Address: 212.27.40.240#53

    Non-authoritative answer:
    Name: test.com
    Address: 205.178.152.103

    I tried with many others DNS and also with a local DNS server (bind) with the same result.

    The output of :

    # dscacheutil -statistics

    Overall Statistics:
    Average Call Time - 1.298089
    Cache Hits - 1813
    Cache Misses - 1888
    Total External Calls - 2662

    Statistics by procedure:

    As you can see, "Average Call Time" is very high, it should be 0.0xxxxx

    Do things get any better if you turn off IPv6?

    Could be something up with your UNIX hosts file. Check it out.

    Interesting problem, ive seen similar issues but they were always due to the local vs external DNS issues.

    Have you got a default gateway set of your router set? i didnt see it in your ifconfig output.

    Im wondering if its a firewall issue with port 53?

    same problem

    I've got the same issues, a webpage title appears almost immediately, the content has to wait, tried Onyx but with no result ... or was it due to Onyx .... I don't remember now anymore ... the problem persists on wireless or wired lan ...

    If the web page title appears instantly then it's unlikely to be a DNS issue as the browser would have to resolve DNS to get the page title.

    what do you suggest? I did a complete maintenance again with Onyx, I'll try later this evening to see if something changed ...

    The two issues sound separate in my opinion as the title of the webpage would mean the DNS resolution had already occurred.

    I had a similar issue in firefox once, have you tried a different web browser?
