Question : Access - Format datatype in Table to have IP Address format

In Access, how does one create a data type in the format property so when entering data, the user is forced to comply with the format ###.###.###.###?

What would be the format?  I'm assuming its a formula I have to give.

Answer : Access - Format datatype in Table to have IP Address format

You would use an Input Mask, but you can only do this on a Form (and users shouldn't be entering data directly in a table anyway). There are a LOT of options for this, so see the help topic regarding this (and Format, since the two go hand-in-hand).
