Why Fork Networking
You deal with us directly
Fork Networking is a small business in Portland, Oregon. We have run our own network and ARIN address space since 1993, and we lease blocks from that space directly to our customers.
We review every lease before it is provisioned, and the same people handle ROA/RPKI, LOAs, SWIP/reassignment, reverse DNS, hosted PTR records, and BGP, whether you announce on your own ASN or route on our network.

Acceptable use
Reviewed leases, clear rules

FAQ
Common questions
Can I announce the leased IPv4 block from my own ASN?
Yes. We can provide ROA/RPKI and LOA support for customers announcing leased IPv4 space from their own ASN, subject to review.
Do you support ROA/RPKI?
Yes. We can create or update ROAs for approved leases so the leased prefix can be originated by the approved ASN.
Do you provide LOAs?
Yes. We can provide a Letter of Authorization when required by your upstream, datacenter, or cloud BYOIP provider.
Do you support reverse DNS?
Yes. We can delegate reverse DNS or host PTR records for leased IPv4 blocks.
Do you support SWIP or reassignment?
Yes, where appropriate. We can handle SWIP/reassignment support for approved customers and use cases.
Can I use the IPs on your network?
Yes. Blocks can be routed on Fork Networking’s infrastructure or announced by your own network, depending on the lease and technical requirements.
Are the IPs clean?
We review reputation before assignment, but no IPv4 provider can guarantee that every third-party reputation database is clean or current. We work with customers on routing, rDNS, ROA/RPKI, and reasonable delisting support when needed.
What uses are not allowed?
Spam, phishing, malware, botnets, credential abuse, scanning abuse, and other abusive or illegal activity are not allowed. Mail, VPN, proxy, and high-risk use cases may require additional review.
