Data downloaded from

aut-num: AS3320
as-name: DTAG
descr: Internet service provider operations
remarks: peering coordinators for AS3320:
remarks: abuse reports should be sent to the contacts
listed in the registry entries for the IP address of the
offending host system
remarks: We share the view that for many networks (including ours:-)
only some abstraction of the actual routing policy should/can
be published in the IRR.
Right now we are abstracting to a very essential minimum.
remarks: the most important and helpful use of the IRR is
to publish what a network will announce to peers and upstream
# we are providing that by means of the AS-set AS3320:AS-DTAG
# which we have been keeping up to date all the time
remarks: we encourage all our neighbors to define and maintain an
AS-set to describe their announcements, and to register
all the routes (and have their customers do so as well)
import: # heavy abstraction hits! well, we are ...
from AS-ANY # neither peering promiscuously
accept ANY # nor accepting all junk routes offered...
remarks: we maintain a list of what our neighbors have told us
about their announcements towards AS3320 - in terms of
AS-set (preferred), AS number, route-set
(and the IRR database used to publish)
remarks: in fact we apply route filters based on this
for all neighbors - as far as feasible
remarks: for data published through the RIPE routing registry
we generate filters automatically
remarks: we consider the integration of RIR and routing registry data
and the application of RPSS authorization a great feature
of the RIPE routing registry
# unfortunately this benefit is not available with any
# other IRR database that we know of...
# and some of the IRR databases allow essentially any garbage
# to be registered without any control - making those databases
# quite useless...
export: to AS3320:AS-CUSTOMERS # but don't publish that list
announce ANY # in general - if they ask for less, we can do
export: to AS-ANY # for peers and others...
announce AS3320:AS-DTAG
# for backwards compatibility the older AS-DTAG
# will be kept around for some more time -
# defined using just members: AS3320:AS-DTAG
# please convert to AS3320:AS-DTAG if you are still
# using the old AS-DTAG
remarks: customers are strongly encouraged to define and maintain
an AS-set that we will include in the definition
of AS3320:AS-DTAG (if we are told the name)
remarks: this will be sufficient to have our peers accept the routes
remarks: in any case peers - and any network in the Internet -
is free to apply some selective policy (e.g. prefix
length based)
# but we do not think that any such selective policy
# will be based on details of our routing policy omitted
# from this aut-num: object
remarks: unfortunately some customers do not provide usable IRR data
we will NOT add to the uncontrolled garbage in the IRR by
proxy registering in some database that requires no
remarks: we advise customers that routes without IRR registration
and not covered by AS3320:AS-DTAG may receive less than
full support by some of our peer networks and other
parts of the Internet
remarks: ==============================================================
IPv6 we do/publish essentially the same like for IPv4
mp-import: afi ipv6.unicast # heavy abstraction...
from AS-ANY # neither peering promiscuously
accept ANY # nor accepting all junk routes offered...
mp-export: afi ipv6.unicast
to AS3320:AS-CUSTOMERS-V6 # but don't publish that list
announce ANY # in general - if they ask for less, we can do
mp-export: afi ipv6.unicast
to AS-ANY # for peers and others...
announce AS3320:AS-DTAG-V6
