rogue

In a dormitory of 550 residents, people often mistakenly set up DHCP servers for the whole network by plugging in their private Wi-Fi routers wrongly. Also recently, someone mistakenly configured their PC to a static IP being the same as that of the default gateway. We use cheap 3Com switches at the moment.

I know that Cisco switches support DHCP snooping to solve the DHCP problem, but that still does not solve the default gateway IP takeover problem.

What sort of switch equipment do real ISP's use so their customers cannot break the network for the other customers?

SQL Server database with clustered GUID PKs - switch clustered index or switch to sequential (comb)

as seen on Stack Overflow - Search for 'Stack Overflow'
We have a database in which all the PKs are GUIDs, and most of the PKs are also the clustered index for the table. We know that this is bad (due to the random nature of GUIDs). So, it seems there are basically two options here (short of throwing out GUIDs as PKs altogether, which we cannot do (at… >>> More
