Re: Hijacking of address blocks assigned to Trafalgar House Group, London UK

Hello!

I've been asked to draw the attention of Network administrators to the recent hijacking of various large blocks of ARIN IP-space: particularly six /16 blocks allocated to the London-based Trafalgar House Group.

Trafalgar House Group (THG): Trafalgar House Group TRAF (NET-144-176-0-0-1) 144.176.0.0/16 Trafalgar House Group THIN1 (NET-144-177-0-0-1) 144.177.0.0/16 Trafalgar House Group THIN3 (NET-144-179-0-0-1) 144.179.0.0/16 Trafalgar House Group THIN4 (NET-144-180-0-0-1) 144.180.0.0/16 Trafalgar House Group THIN5 (NET-144-181-0-0-1) 144.181.0.0/16 Trafalgar House Group THIN2 (NET-158-181-0-0-1) 158.181.0.0/16

An example of why allocation boundary based prefix-filters are a good thing.
