Summary
Razorblue
hosting isp business telecom
Forty-two neighbours for four thousand addresses, and every one of them answers to the same template.
What it's used for
- A managed services and hosting provider. Nine IPv4 prefixes and one IPv6 prefix announced from the United Kingdom, four thousand and ninety-six addresses, across forty-two observed BGP neighbours.
Notable
- Seventeen of eighteen sampled addresses answer, and every name is the four octets hyphenated, followed by the word for a fixed address, followed by the company domain.
- That includes the network and broadcast addresses of each block, which get the same name as any other address.
- All nine blocks share one netname convention with seven different allocation dates, spread across more than a decade.
- Every block lists the company's own abuse handler rather than the registry's generic role.
- The IPv6 announcement is a
/30, larger than the standard opening allocation. - Nine separate blocks from eight unrelated ranges make up four thousand addresses.
Interesting
- Forty-two neighbours is ten times what a network this size usually carries. The address count measures what a provider holds; the neighbour count measures how many places it chose to connect, and those are independent decisions.
- Generating names for every address in a block, structural ones included, is the cheapest correct answer. It costs one template, it never goes stale, and it tells a reader nothing beyond the address they already had.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,772 prefixes, as published 2026-10-15. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
