AS218506 / IPv4 wanted

// IPv4 ACQUISITION

Looking for
dirty IPv4 space

/24 or larger, including old, unused, blacklisted or difficult-to-sell blocks.

I want to buy IPv4 space for AS218506 infrastructure, BGP and peering. I also want to study what it takes to reuse blocks with reputation problems.

Previous abuse or blacklist listings do not rule a block out. I will check its history before agreeing to a transfer.

The space must be legitimate, transferable and globally routable.

01 / THE BRIEF

What we are looking for

/24 or larger

Minimum size /24. Larger blocks are welcome.

Any RIR

RIPE NCC, ARIN, APNIC, LACNIC or AFRINIC. Transfers must meet the applicable RIR rules.

Transferable

Legally transferable or otherwise legitimately assignable address space.

Globally routable

Usable for normal Internet routing.

Dirty history is fine

Blacklist history, spam reputation or prior abuse is not automatically a dealbreaker.

Purchase preferred

Acquisition rather than long-term lease. Unusual opportunities can still be discussed.

02 / HISTORY WELCOME

Blocks with a history

I am interested in blocks from discontinued hosting or ISP infrastructure, including space with reputation problems that make it difficult to sell.

Both clean and reputation-damaged space are welcome.
  • Old hosting history
  • Mail reputation problems
  • Stale PTR records
  • Previous abuse
  • Legacy routing history
  • Old ISP allocations
  • Abandoned infrastructure
  • Poor geolocation metadata
  • Blacklist listings
  • Long periods of inactivity

03 / PURPOSE

Why AS218506 wants it

Network infrastructure

IPv4 connectivity for AS218506 services and infrastructure.

BGP & peering

Announce and use the space through transit, bilateral peerings and Internet Exchange connections.

Reputation research

Measure how IPv4 reputation changes over time and which signals persist.

Rehabilitation

Build processes around cleanup, monitoring, documentation and responsible reuse.

Reputation cannot always be restored. Delisting, recovery and acceptance by external providers are never guaranteed.

04 / THE PROCESS

Acquisition and rehabilitation process

  1. Acquire

    Agree a legitimate acquisition or transfer, subject to verification.

  2. Verify ownership

    Check RIR ownership, transfer eligibility, routing history, IRR and RPKI before completion.

  3. Quarantine

    Keep the block away from uncontrolled customer or mail traffic.

  4. Clean registration

    Correct stale DNS, PTR records and outdated registration metadata where possible.

  5. Route under AS218506

    Prepare authorisations and announce the block under AS218506.

  6. Monitor reputation

    Watch routing, reputation, abuse signals and blocklists.

  7. Resolve abuse issues

    Investigate historical reports and request corrections or delisting where appropriate.

  8. Document results

    Record changes, measurements and unresolved issues.

05 / CONTROLLED REUSE

What happens after acquisition

Newly acquired IPv4 space will not immediately be placed into production workloads.

It may first be placed in a controlled environment where routing, DNS, reverse DNS, reputation and abuse signals can be monitored.

06 / QUICK CHECK

Think you have a block?

  • /24 or larger?
  • Transferable?
  • Globally routable?
  • Unused or underused?
  • Difficult reputation/history?
  • You want to sell it?

If this describes your block, email me. I will need to verify ownership, transfer eligibility and routability.

Email AS218506

What to include

Send whatever you know. None of these fields is required for an initial conversation.

  • Prefix and RIR
  • Current holder
  • Current origin ASN
  • Whether the block is currently announced
  • Transfer status
  • Known reputation problems
  • Asking price
  • Preferred transfer process
Even if you only know the prefix, send it over.

07 / TRANSPARENCY

Ownership and transfer checks

AS218506 will verify all space before any transaction. That includes RIR ownership, transfer eligibility, route history, IRR, RPKI, abuse history, major blocklists, geolocation, reverse DNS and historical origin ASNs.

AS218506 does not acquire hijacked, disputed or improperly assigned address space.

Got an unwanted IPv4 block?

Unused space and blocks with reputation problems welcome.

If it is legitimate, transferable and globally routable, I am interested.
