InetAddress get IP inconsistency

Question

I'm trying to go through a list of URL's and grab their IP but what I'm noticing is sometimes it will get hung up on a website and never move on and other times it will skip a bunch of websites. Does anyone know what's causing this?

for (String site : sites) {

    try {
        address = InetAddress.getByName(new URL(site).getHost()).getHostAddress();
    } catch (Exception e) {
        System.out.println(e);
    }

    IPList.put(address, site);
    publish(site);

}

EDIT: I've narrowed the problem down to the publish method. It seems like it's finishing the for loop before it has a chance to publish everything and then it just stops...

EDIT2: Figured it out, small mistake on my end. Thanks.

Try this:

private ArrayList<String> ips = new ArrayList<String>();

for (String site : sites) {
try {
    address = InetAddress.getByName(new URL(site).getHost());
} catch (Exception e) {
    System.out.println(e);
}
String ip = address.getHostAddress();
ips.add(ip);

}
