A successful IPv4 transfer may require documentation showing who the parties are, who is authorized to act for them, which IPv4 resources are involved, whether the source is entitled to transfer those resources, and whether the recipient satisfies the requirements of the applicable Regional Internet Registry (RIR). The exact documentRead more

]]> What Is NAS? Network Attached Storage and How It Reaches the Internet https://blog.i.lease/what-is-nas/ Mon, 31 Aug 2026 14:09:55 +0000 https://blog.i.lease/?p=17231 NAS stands for Network Attached Storage. It is a dedicated storage device that connects to a network and serves files to every authorised computer, server, or application on that network, instead of storing data on individual machines. Where a normal external drive belongs to one computer, a NAS belongs to the whole network. For a business, that difference matters operationally. A NAS turns storage from a per-device problem intoRead more

]]> What Is a Botnet? How Compromised Hosts Turn Your IP Space Into Attack Infrastructure https://blog.i.lease/what-is-a-botnet/ Thu, 27 Aug 2026 03:27:03 +0000 https://blog.i.lease/?p=17054 A botnet is a network of compromised computers or devices running malicious software that lets a single operator control them all remotely. Each infected machine is a “bot,” the person controlling them is the “bot herder,” and the channel through which commands are issued is called command and control (C2). Together they form a distributed platform that can be pointed at any target the operator chooses. Botnets are usuallyRead more

Handling Abuse Reports for Your IP Space https://blog.i.lease/network-abuse-handling-abuse-reports/ Wed, 26 Aug 2026 03:30:20 +0000 https://blog.i.lease/?p=16963 Network abuse is the use of IP address space to conduct harmful activity spam, phishing, malware distribution, brute-force attacks, scanning, or participating in attacks and abuse reports are the notifications sent to whoever is responsible for that space when it happens. Those reports arrive at the abuse contact registered for the address block, which means they arrive at you if you hold or manage the space, regardless of whoRead more

]]> What Happens to IPv4 Records After an IP Address Transfer? https://blog.i.lease/what-happens-to-ipv4-records-after-an-ip-address-transfer/ Tue, 25 Aug 2026 06:42:19 +0000 https://blog.i.lease/?p=16912 Completing an IPv4 transfer does more than move address space from one organization to another. It changes the administrative relationship around the IPv4 block—and that can affect multiple records and services associated with the resource. After an IPv4 transfer, organizations may need to review or update: RIR registration records WHOIS and RDAP information Organization and contact details Abuse contacts RPKI certificates and ROAs Internet Routing Registry (IRR) objects ReverseRead more

LOA vs ROA and What to Verify https://blog.i.lease/letter-of-authorization-ip-leasing/ Thu, 20 Aug 2026 15:42:10 +0000 https://blog.i.lease/?p=16720 A Letter of Authorization (LOA) is a formal document in which the registered holder of an IP address block authorizes another party to announce that address space from a specified Autonomous System Number. It is the written permission that connects a contractual right to use address space with the technical act of routing it — and without it, upstream providers will generally refuse to accept your announcements. That refusalRead more

Block Sizes (/24, /23, /22, /21, /20) and Sizing Guide https://blog.i.lease/how-much-ipv4-space-do-you-need/ Wed, 19 Aug 2026 07:24:41 +0000 https://blog.i.lease/?p=16718 Most businesses should size IPv4 by starting at a /24 — the smallest block the global Internet will reliably route — and sizing up from there based on how many addresses their actual services consume, plus room for growth. A /24 provides 256 addresses; each step up roughly doubles that. The right size is the one that covers your real address usage and near-term growth without leaving you payingRead more

The difference is origin: one comes from infrastructure built to run servers, the other from a connection built to serve an end user. That single distinction shapes how the rest of the Internet treats traffic fromRead more

The reason is that an IPv4 transaction does not exist only at the commercial layer. The address block is also registered within a Regional Internet Registry framework, and the applicable policies can affect whether the resource is currently transferable, what the recipient must prepare, which records needRead more

]]> Proxy vs VPN: What’s the Difference and Which Do You Need? https://blog.i.lease/proxy-vs-vpn/ Sat, 15 Aug 2026 21:45:32 +0000 https://blog.i.lease/?p=16702 A proxy reroutes traffic for a specific application through an intermediary server, while a VPN routes and encrypts all of a device’s traffic through a secure tunnel. The short version: a proxy changes the apparent source of some of your traffic; a VPN changes and protects the source of all of it. That difference in scope and encryption is the core of the comparison, and it usually points clearlyRead more
