About this network

EXASCALE is operated by Exascale Ltd.

What it's used for

• The address space carries residential fibre-to-the-premises traffic, evidenced by the reverse DNS record cust-185-20-54-254.fttp.tel.uk.as61049.net and netnames such as UK-EXASCALE-20130301 and UK-EXASCALE-20170321.
• The AS announces 5120 IPv4 addresses across 11 prefixes and 12 IPv6 prefixes, while maintaining 1011 observed neighbours; this high neighbour-to-address ratio indicates a transit and peering role alongside its access network.
• Traffic from this AS consists of subscriber eyeballs for multi-gig full fibre broadband services, with speeds up to 2.5Gbps, delivered via Openreach and CityFibre networks across the United Kingdom.

Notable

• Registrants largely align with the announcer, including Exascale Ltd and Exascale Limited, though some prefixes are registered to third parties like Fulcrum Data Systems Ltd and Event WiFi & Communications Ltd.
• The address inventory is fragmented into multiple /22 and /24 blocks, with some prefixes associated with specific locations like Telford and others linked to DSL or event communications.
