All,
WRT the below route object, DataBank does announce IP space for Hoechst Celanese
Corporation as they are a direct customer of ours:
$ whois -h whois.radb.net 148.163.0.0
route: 148.163.0.0/16
descr: /16 for Celanese
origin: AS13767
mnt-by: DBANK-MNT
changed: jpope@databank.com 20090818
source: LEVEL3
Currently, we only announce/originate the following prefixes via BGP:
148.163.178.0/24
148.163.179.0/24
via our providers, Level3 and Sprint. We asked our providers to relax their
filters for the whole /16, since Celanese owns that IP space. That may or may
not be a good idea, depending on your view of network management. We did this
in case our customer needed to announce new networks which would save us the
time/work of placing more/new route objects in the registry. We have the
appropriate LOA for this network which is validated through face-to-face
meetings with their network engineers and representatives.
DataBank is very sensitive to network abuse; we have an AUP in place with all of
our customers and will always work hard to enforce it to prevent network abuse.
I apologize that I didn't respond sooner, but I have gotten behind on my NANOG
reading.
Thank you,
Jason Pope
