I'd be looking for something like JavaScript's split() function - which
works like this:

ipAddy = "123.456.4.12";
a = ipAddy.split('.');

which would give you an array like this:

a[0] = 123;
a[1] = 456;
a[2] = 4;
a[3] = 12;

is there any such thing/function in SQL?

or do a view of the ip address table and push them into columns as
numerics? something like that?

just spitballing here.

this surely must be something that's been thought of by database gurus.
must be someone tackled this...

If you're ever in Los Angeles, and you have a hankering for a classic
hot dog. Get yer ass down to Pink's - a classic, greasy, chili-laden
tradition - world famous and in Hollywood itself.

My appetite has been terrible lately. (Psychosocial angst is great for
weight loss!) But I could really go for one of their big ol' dogs -
laden with onions and sauerkraut and chili.

And even fries. I don't usually, but I think I'd splurge for a Pink's dog.

(note to self: I probably have lots of positive associations with Pink's
because Jenny and I used to go there. Also, we saw Puck (of MTV's Real
World fame) at Pink's once. Leading to our joke-to-ourselves catchphrase
-- "I saw Puck at Pink's!" -- which is amazingly fun to say repeatedly.
