Leasing /22 blocks

2017-06-01 Thread Security Admin (NetSec)
Recently had someone offer to lease some IPv4 address space from me. Have never done that before. I thought I would ask the group what a reasonable monthly rate for a /22 in the United States might be. Thanks in advance! Ed(ward) Ray

A few of our exchange IPs get blocked intermittently, but only by ATT. Ips are clean, no issues, we’re diligent about finding and fixing these types of issues as it has a large impact. It would be very helpful to know why the IP below got blocked so we can find and fix the problem to prevent fu

Best practices for sending network maintenance notifications

2016-04-06 Thread Dan Mahoney, System Admin

Apologies for the non-personal email address, but I don't want to give our attacker any additional information than I need to. I'd be happy to send personal contact/ASN information to any nanog admins or regular members of nanog if it's useful. Over the past year or so, we (a decent sized tier 2

Squeezing IPs out of ARIN

2012-04-24 Thread admin
Anyone have any tips for getting IPs from ARIN? For an end-user allocation they are requesting that we provide customer names for existing allocations, which is information that will take a while to obtain. They are insisting that this is standard process and something that everyone does when r

Hello all, While recently trying to debug a CEF issue, I found a good number of packets in my "debug cef drops" output that were all directed at 198.32.64.12 (which I see as being allocated to ep.net but completely unused). Sep 2 22:03:25: CEF-Drop: Packet for 198.32.64.12 -- no route Sep

Hey all... Apologies if this is off-topic, but it appears something insidious (or at least unfortunate) has happened to the netblock allocation for a company I'm working with -- it's basically dropped off the face of the planet, fairly recently. Conveniently, late on a friday, is when it was
