      Any idea what this log entry means:

      dhcpd: parse_option_buffer: option www-server (121) larger than buffer.

        some malformed, weird dhcp packets coming in with custom options set?
        Is there a dhcp lease just before or after, so you can see what device is sending the dhcp packet?

          There are these entries before the log entry mentioned:

          Sep 10 10:42:39 dhclient[60048]: bound to 9x.8x.1xx.2xx – renewal in 14400 seconds.
          Sep 10 10:42:39 dhclient[60048]: DHCPACK from 6x.1xx.3x.2xx
          Sep 10 10:42:39 dhclient[60048]: SENDING DIRECT
          Sep 10 10:42:39 dhclient[60048]: DHCPREQUEST on em0 to 6x.1xx.3x.2xx port 67

          I replaced some of the numbers with x's.  The 9x.8x.1xx.2xx is my WAN IP address.  I think the second address is my ISP.  I am using 8.8.8.8 and 8.8.4.4 for DNS.

          I also see something like this every once in a while (IP is not always the same):  kernel: arplookup 100.183.158.141 failed: host is not on local network

          Looking right before the first problem entry after a re-boot is the following entries:

          root: IP-Blocklist was found not running
          root: Countryblock was found not running

          I think this is the process where it makes sure those packages are running.

            Your ISP is handing some options to you in the DHCP lease it seems, nothing to be worried about, usually stuff for their own equipment.
