Reliance Jio orignating Charter’s /16 pool


Just noticed that Reliance Jio (AS55836) seems to be originating a /16 which is for Charter Communications (AS20115) –



This shows Reliance Jio’s ASN AS55836 announcing 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


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, and 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 (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.

A visit to 221b Baker Street

So last week I couldn’t hold off my curiosity about world famous address “221b Baker Street”. I passed “Baker Street” tube station quite a few times and finally decided to just look for it. 🙂

By time I reached the street it was lightly raining and I found few other (curious) people like me standing outside 221b Baker Street. It has got a museum for Sherlock Holmes (though was closed by the time I reached).


Some pictures of the visit


It was fun visit and I enjoyed it by just looking from outside. 🙂
