Remove string between dash (-) and the first dot (.)

Question

I have many web addresses which are including some special interface names, which I would like to remove. Examples:

aaaaaaa-INT1.aaaa.aaaa.com
bbbbbbb-INT2.bbbb.bbbb.com
ccccccc-INT.cccc.cccc.com

So my expected result after sed should be:

aaaaaaa.aaaa.aaaa.com
bbbbbbb.bbbb.bbbb.com
ccccccc.cccc.cccc.com

I have tried this, but it doesnt work:

sed 's/-.*^.//'

Any suggestion please?

To remove the first dash and everything before the first period:

$ sed 's/-[^.]*//' file
aaaaaaa.aaaa.aaaa.com
bbbbbbb.bbbb.bbbb.com
ccccccc.cccc.cccc.com
