Extract Last Word in a String with Anchor Start and Anchor End

Original regex at https://www.regextester.com/103299. I added a check for US country code in front of the area code

This RE is divided into four parts. The first three parts are acceptable numbers from 0 to 255 followed by "." The last part is an acceptable number but not followed by "."
