Internode residential. Doesn’t look like TPG is involved at all.

I think you mean the other way around, TPG are getting the route in the US, its SAU via BlackLotus (currently anyway)

Gday Guys

 

It seems (Atleast to my eyes) that TPG are leaking the routes for 203.27.101.0/24 overseas?

 

Can anybody else on-list confirm this before I contact them direct?

 

An IP you can traceroute is 203.27.101.1

 

 

TIA
