> IP Range and IPStartRange will be something like X.X.X.X I gather? No, the IP addresses are converted into dotless form and essentially, a bigint is required in SQL Server and decimal(20,0) is used in MySQL. Indexing integer based datatypes is as good as it gets for this process I believe... This point was implied in the table design that I posted.

Only if the query actually referenced it but in the case I have stated adding a column like that is irrelevant and takes up space in the DB that can be used for other things... > Note that DB design and methodologies are independent of the RDMS Yes, I know this. I used SQL Server as a comparative example. Given that MySQL is meant to be of a reasonably high performance, I would have expected it to be closer to SQL Server than I have found in this instance. > performance however, isn't if mySQL is slow then it's down to mySQL and its > implementation of SELECT logic internally etc... I agree, hence the questions regarding how would you optimise this for MySQL.
