  17. Things for you to do • Consider giving the internal search engine access to material currently excluded from indexing • User Agent isUltraseek (internal search; webmaster@ucs.cam.ac.uk) • Set-up 192.153.213.0 – 192.153.213.255 as being 'outside the University' – the external search engine will use one of these addresses and will NOT have a 'cam.ac.uk' name • Details athttp://www.cam.ac.uk/cs/web-search/developments.html
