About this network

BYTEMARK-AS is operated by Iomart Managed Services Limited, the corporate entity behind the Bytemark hosting brand.

What it's used for

• The address space carries hosting and managed services infrastructure, evidenced by netnames like UK-RAPIDSWITCH and UK-WEBHOSTING-UK, and reverse DNS entries referencing bytemark.co.uk and bigv.io.
• With 55,808 IPv4 addresses announced across 21 prefixes and only 1 observed neighbour, the network functions as a hosting provider rather than a transit carrier.

Notable

• Registrants are consistent with the announcer, with most prefixes registered to Iomart Managed Services Limited, while a few smaller blocks are registered to Hyperslice Network Team and eUKhost LTD.
• Bytemark was acquired by Iomart, which now operates the service under the Iomart Managed Services brand while retaining the original AS handle.
• The inventory includes a mix of large /18 and /19 blocks alongside smaller /22 and /24 prefixes, reflecting a consolidated corporate estate.
