in this case the customer has their own disconnected deployment, and they are asking 396982 to announce some subset of 
their prefixes such that gcp gets that traffic.   Yes, this is the case. GCP is advertising our prefix on our behalf.

assignment from ARIN. We have our infrastructure in GCP (Google Cloud Platform) where we started using BYOIP 
functionality (Google advertises our IPs). We followed their recommendation with ROA configuration in ARIN   
cloud.google.com https://cloud.google.com/vpc/docs/bring-your-own-ip#live-migration-recommendations   but they 
don't mention if IRR (whois database) should be updated as   The roa is really for two reasons:     1) tell Google 
you actually control that asset.    2) tell the world that 396982 is permitted to originate that prefix.   Use of irr 
data is nice, but not required here...   This is understood, however due to missing entries in IRR those tools flag 
those prefixes as suspicious to mismatch between what's advertised and what's in ARIN database. My goal is to 
avoid it.   I'm looking for information on what's community approach for this. How this should be handled?  
well. I've checked with their support and they said no additional changes need to be done there.  But currently we 
are in situation where ARIN's whois contains entry for our prefix with our own ASN and Google advertised to RADb 
entry for our prefixes with their own ASN.   I don't believe to robots at google are supposed to register irr data 
for byoip customers... Can you mail me off list and I can go do a.little digging? ;)   I haven't seen info on that 
in their documentation, but we did notice a new entry in RADb for prefix that we added in GCP that had MAINT set to 
Google.   When we use online tools like   irrexplorer.nlnog.net https://irrexplorer.nlnog.net/   or Cisco's 
CrossWork Cloud (former BGPmon), they mark our prefixes due to mismatch of ASN in those 2 databases.  We haven't 
observed any routing issues so far (i.e. ISP not importing our prefixes), but we aim to sort this out for better 
credibility. I'm wondering what's community approach for updating whois databases when using BYOIP 
functionality with Cloud providers and if there is a risk of any potential impact if we were to change information in 
ARIN.  Thanks
