I got a call today from them around 6:20pm.  I was not home to take the call, but when I noticed that they had not left a message, I called them back.

I got an automated voice telling me it was from eNom.  I recently transferred a website over to their service and figure that is how they got my number.  If they were calling to sell me something or not, I am not sure, but I bet this number gets hots since AOL is pushing their @yournamehere deal over to them.

Hope this helps.

Just want to confirm that this is eNom. I recently let a domain with this registrar expire which prompted the call.

This is confirmed 100%.  This is enom.com.  I get calls from them every so often as I am a reseller with them.  I "never" get telemarketing/sales calls from them, they are always service calls dealing with my accounts.  So all good in my book.
