This shows Reliance Jio’s ASN AS55836 announcing 47.35.0.0/16. Charter Communications (AS20115) is originating multiple of /18s out of the same pool.

Let’s look for whois record of this /16 pool: https://whois.arin.net/rest/net/NET-47-32-0-0-1

NetRange: 47.32.0.0 - 47.51.255.255
CIDR: 47.32.0.0/12, 47.48.0.0/14
NetName: CC04
NetHandle: NET-47-32-0-0-1
Parent: NET47 (NET-47-0-0-0-0)
NetType: Direct Allocation

It seems highly unlikely that this pool has been transferred over to Jio and hence it’s highly likely that Reliance Jio is falsely advertising this pool. Possible reason for such mistake can be because they have got 47.29.0.0/16, 47.30.0.0/16 and 47.31.0.0/16 but beyond that there are few Charter Pools. So likely someone just mistyped an IP. Another possible reason for such mistype can be that they have also got 49.35.0.0/16 (it’s 49, not 47). What is much more fascinating is that they even have a RADB route object registered for the same.

World of BGP is interesting!

As per update from Mr Morlay Gosh from Reliance Jio on SANOG mailing list. This was mistake and they are removing the same.
