Under
...
some
...
circumstances,
...
we
...
may
...
need
...
to
...
remove
...
a
...
host
...
from
...
the
...
network
...
and
...
prevent
...
it
...
from
...
having
...
access
...
to
...
Tufts
...
network
...
resources.
...
Some
...
reasons
...
could
...
be
...
that
...
we
...
receive
...
a
...
notice
...
of
...
DMCA
...
violation
...
associated
...
with
...
a
...
certain
...
IP,
...
or
...
if
...
a
...
host
...
is
...
trying
...
to
...
spread
...
malware,
...
or
...
if
...
a
...
host
...
is
...
just
...
behaving
...
in
...
a
...
way
...
that
...
prevents
...
the
...
network
...
and/or
...
the
...
hosts
...
on
...
it
...
from
...
operating
...
normally.
...
When
...
a
...
blacklisted
...
host
...
connects
...
to
...
the
...
network
...
and
...
asks
...
Bluecat
...
for
...
a
...
DHCP
...
address,
...
Bluecat
...
provides
...
an
...
IP
...
address
...
in
...
a
...
special
...
range
...
that
...
indicates
...
it's
...
a
...
restricted
...
network.
...
The
...
only
...
thing
...
users
...
should
...
be
...
able
...
to
...
get
...
to
...
from
...
a
...
restricted/blacklisted
...
IP
...
address
...
is
...
the
...
restricted

portal

page.
FSPs can blacklist a host. However, they cannot remove a host from the blacklist. Blacklist removals need to go through Info Security. Please be careful and do not blacklist hosts inappropriately.
To blacklist a host, search on the MAC address or the username the MAC is registered to, and select the "blacklist" button under the host listing. If you wish to simply delete an obsolete registration entry, you can also do that from this page and select the "delete" button. Blacklisted hosts cannot be deleted while they are on the blacklist.
The registration listing will also show the time a host was registered and when the registration expires.
