I have a little experience in

  • Embedded and realtime systems programming in C

And even less in

  • Makefiles
  • Linux/Unix, shell scripting

And not much else really...

comment BIND result validity
the modem is set to resolve using OpenDNS, not the ISP. I guess it is caching, as the second and subsequent calls to "dig ibm.com" with the modem condigured as the computer's DNS server are in the 3-30ms range while the first is in the 150-500ms range (round trip to OpenDNS). With only response times to go on, this is just speculation, of course :-)

comment BIND result validity
@JdeBP: thanks! I doubted you, but you are right. I unplugged the Ethernet cable and tried digging ibm.com again. To my surprise, this had the same result; hundreds of ms response time the first time and a few ms if repeated quickly. I imagine there is some disk access going on that is slowing it down - but there I am jumping to conclusions again. (Interestingly, ping can't resolve ibm.com with the cable unplugged, implying that it is not using the local server!)

Added update to question after initial assumption turns out false.

Thanks. There must be some other reason for the request being repeated so soon. Actually it is more like 5s, not the 10-20s I stated earlier - edited above.

comment Odd entries in DNS lookup log
Thanks very much and thanks for the link - interesting :-) Hoping not to try your patience, how does one determine the FD00::/7 from the long string of numbers? and who/what/where might be using IPv6 on the box?
