     [ http://issues.apache.org/jira/browse/NUTCH-289?page=all ]

Enis Soztutar updated NUTCH-289:
--------------------------------

    Attachment: ipInCrawlDatumDraftV5.1.patch

The version 5 patch does not run on the current build. So i have fixed it and resend the patch(did not changed any code). I think this patch should be included in the trunk.

> If the CrawlDatum stored the IP address of the host of it's URL, then one could:
> - partition fetch lists on the basis of IP address, for better politeness;
> - truncate pages to fetch per IP address, rather than just hostname.  This would be a good way to limit the impact of domain spammers.
> The IP addresses could be resolved when a CrawlDatum is first created for a new outlink, or perhaps during CrawlDB update.
