Problem with opkg update !

Hi, Could I receive some advice about updating the BBB with opkg update. I reflashed the eMMc with Cloud9 GNOME Image 2013.09.04. The OS is Angstrom v2012.12 (Core edition), Built from branch: angstrom-staging-yocto1.3. I am receiving the following error: Example of error without modifying the hosts file

Downloading http://feeds.angstrom-distribution.org/feeds/v2012.12/ipk/eglibc/armv7a-vfp-neon/python/Packages.gz.

wget: bad address ‘feeds.angstrom-distribution.org

Collected errors:

And After modifying the host files with 140.211.169.179 feeds.angstrom-distribution.org I am receiving the following errors:

Downloading http://feeds.angstrom-distribution.org/feeds/v2012.12/ipk/eglibc/armv7a-vfp-neon/python/Packages.gz.

wget: can’t connect to remote host (140.211.169.179): Network is unreachable

Collected errors:

Would be great if somebody have some idea to solve this problem!
