As usual, there's a simple explanation
IT manager pilot fish puts in an order with an internet provider to boost bandwidth and get a bigger block of IP addresses, and it looks like everything is running on rails.
“Forms were completed and everything was going smoothly,” fish says. “I received a box with a modem on Monday as promised. I got it racked up and powered ahead of time.
“That way, when the ISP tech arrived on Wednesday afternoon, all he would really need to do is swing the connection from the old modem to the new one and call into the ISP’s network operations center to have them assign the new IP block to the new modem. Then I could assign the IP addresses to our firewall.”
