When I was using DHCP, my lease time was 86400 (24 hours). In the
threads on comp.os.linux.networking, "Bit Twister" had me switch over to
a statically assigned IP address of 192.168.1.150. My most recent DHCP
lease expired on Nov. 7. Despite this, "Bit Twister" insisted as a
condition for his continued assistance, that I clear out
my /var/lib/dhclient/dhclient-eth0.leases file.

Here is a sample of what I've concluded to be Verizon probing frequently
to see if I'm using a server. Do you think my conclusion is wrong?
