About this network

LBH-AS is operated by London Borough of Hackney.

What it's used for

• The address space carries municipal network traffic, with all nine IPv4 prefixes registered under the netname Virgin-Media-LBH and registrant Virgin Media; Telewest Broadband Business Internet.
• The AS announces 65,536 IPv4 addresses across 9 prefixes while maintaining only 1 observed neighbour, a ratio indicative of a small, isolated internal network rather than a transit or large-scale access provider.
• Traffic from this AS consists of internal communications and services for the London Borough of Hackney council, including administrative systems and public-facing municipal infrastructure.

Notable

• The registrant data lists Virgin Media; Telewest Broadband Business Internet for all prefixes, which reflects the historical acquisition of Telewest by Virgin Media and the subsequent branding of their business internet services, rather than a change in the AS holder.
• The inventory consists of a single contiguous block within 156.61.0.0/17, subdivided into nine smaller prefixes ranging from /17 to /24, typical of a corporate or municipal estate segmented for internal management.
