About this network

WORLD-FIRST-COMMUNICATION-LTD is operated by World First Communication Ltd.

What it's used for

• The address space carries residential broadband traffic, evidenced by the reverse DNS record gateway.b3cables.co.uk and the operator's self-identification as a Cable/DSL/ISP provider.
• The AS announces 28,928 IPv4 addresses across 72 prefixes and 1 IPv6 prefix, while maintaining 19 observed routing neighbours; this ratio of address space to peering partners indicates an access network rather than a transit provider.
• Traffic from this AS consists of subscriber eyeballs accessing the internet via broadband connections, supporting streaming, remote work, and general web usage for residential customers in the United Kingdom.

Notable

• Registrant data is mixed; while several prefixes list WORLD FIRST COMMUNICATION LTD or Catixs Ltd, others are registered to third parties such as GTT - EMEA Ltd., Apex Innovations Group LLC, GCI Network Solutions Limited, GLOBAL NETWORK AGENCY INC, TechAdept LLC, and EQUINOX TECHNOLOGIES LLC.
• The address inventory includes blocks originally allocated to other operators, suggesting the space was acquired or leased from previous holders like GTT and GCI Network Solutions.
• The AS was first seen in routing tables on 2025-03-04, indicating a relatively recent entry into the global routing table.
