    Curious why configd connects to 10.136.xx.x on every startup? What is 10.136.xx.x?

    Connection report for process: configd (/usr/sbin/configd)
    Total: 0 Bytes sent, 303 Bytes received
    10.136.xx.x (10.136.xx.x), Port 67 (bootps), Protocol 17 (UDP), 0 Bytes sent, 303 Bytes received

    It's probably invoking this agent:

    What do you get if you open Network Utility (in Utilities), select Lookup, enter [that IP address] and click on Lookup?

    It seems that configd is just obtaining info related to IP configuration. I wouldn't worry about this.

    Technically, the 10 network belongs to nobody. It is one of the address blocks used for private networks. DiG is telling you Answer: 0, which means it didn't find a reverse map. The 68.115.xx.xx address is the DNS server at your ISP that replied that it could not find an answer, even when contacting authoritative DNS servers prisoner.iana.org. and hostmaster.root-servers.org. As LPZ said, it is probably the IP address of the DHCP server that gave you your IP address (DHCP is an extension to and uses the same port as BOOTP - UDP 67).
