When I attempted to install on a machine running Node v8, I got the following:
npm WARN notsup Unsupported engine for ip-address@7.1.0: wanted: {"node":">= 10"} (current: {"node":"8.17.0","npm":"6.13.4"}) npm WARN notsup Not compatible with your version of node/npm: ip-address@7.1.0
It looks like even though your package supports Node version >=5.0.0, your dependency ip-address@7.1.0 requires Node version >=10.0.0. In addition to the change I suggested, you may want to manage your published versions of your package so the right one is installed for the right Node version.
