I have a BGP router which announces my networks, but I need announce its IP address in BGP. How I can do that?

Ok, I've found, I've create an loopback interface and add it with network command into my bgp announce.

Glad you resolved this issue. Please be sure to mark your answer as "accepted" when you are able. – jscott Jul 27 '12 at 18:27
Normally your upstream ISP will configure a /30 link to you from their address space. You form a EBGP peer with their router over this /30 link. Then any BGP announcements you make to that ISP have a next-hop of your end of the /30 point to point.
Your upstream ISPr selling you BGP should really help walk you through this.

Googling for "Cisco bgp configuration" returns this document http://www.cisco.com/en/US/tech/tk365/technologies_configuration_example09186a008009456d.shtml
Probably is the right thing to do.

Could you please elaborate on what you are trying to achieve?
It is not sensible to announce a single IP address via BGP - upstream routers will filter any range smaller than /25, and hence the address will not be routable.
