•We
notice that using hostnames alone may be problematic
–Especially when a host has multiple hostnames or is represented by an IP address with dissimilar distributions
–e.g. www.informatik.uni-trier.de, ftp.informatik.uni-trier.de and 136.199.54.185 are the same host
•Therefore,
we also experimented with
–Domain (e.g. uni-trier.de)
–Resolving hostnames to IP addresses
