Your ISP has a DHCP server. They can assign IPs by modem MAC addresses. When your modem comes online, it communicates to the network indicating it is looking for an IP address. The DHCP server listens to this communication and starts talking to the modem. The modem then transmits its MAC address to the DHCP server.
A storm that has dumped 60 inches of snow on Erie since Sunday night will bring another heavy blast of lake-effect snow to portions of Erie County Tuesday night and Wednesday. The National Weather Service in Cleveland is forecasting possible snow accumulation of an additional 7 inches Tuesday night and into the early morning Wednesday.
Reports of 7 to 9 inches were common across the Twin Cities area around Sunday afternoon. Rochester's 292-day streak of days without at least an inch of snow fell around 6 a.m. Sunday when its airport recorded 1.1 inches. In Wisconsin, 7 inches were recorded near Grantsburg while nearly 5 inches fell in La Crosse. It was the first snowfall greater than 2 inches that La Crosse had seen since Jan. 21.
