» JEAH Communications, LLC
JEAH is definitely one of the most well-known providers in the business. You may remember the raid that took down FOONET - JEAH is one of the few providers who "survived" that situation, and even thrived afterward. Their current datacenter is local to them.. in downtown Chicago. They're housed on multiple 1gbit connections to Cogent, Telia, and Abovenet. JEAH's denial of service attack filtering has blocking/limiting at both edge and internal sources. They offer BNC/proxy accounts, shell accounts, IRCD accounts, web hosting, domain registration, and merchant services. Prices are competitive, starting at $4.17/month. I'd say JEAH's strong point is their virtual hosts for IRC. Most of their virtual hosts are short and clever. They own hundreds of domain names. Their customer service is also top-notch (a rarity) - you can always get in touch with the owner.. no matter what the time and what the need. JEAH accepts all major credit cards, money orders, checks, electronic checks, Western Union transfers, bank transfers, and US cash.

» Lomag Internet Services, LLC
Lomag is another "old skewler", having been around for nearly 10 years now. They lease their own dedicated multiple 100mpbs bandwidth space at AboveNet in New York, which is within only a few hours driving time from their physical location. Lomag has recently acquired several smaller providers, making them one of the largest, allowing them to boast 9 servers. You will have to choose the server which has the virtual hosts you desire - as their vhost domains are spread out among the 9. For that reason, Lomag might not be your best choice in that nature, but for a stable hub on a botnet, they definitely have the speed and connectivity desired. Lomag accepts US cash, money orders, checks, electronic checks, Western Union transfers, and Visa/Mastercard.

» KIRE, L.L.C. DBA KIRE.NET
KIRE is also one of the "originals", probably totaling off the top 3 oldest actually. They previously had their own datacenter on-site, but have since moved to a colocation setup with T1 connectivity provided by Sprintlink. Their servers are housed in Virginia Beach, Virginia which is where their office is as well. At its peak, KIRE boasted 12 servers - currently having only 6. KIREnet's best feature is that you can get an account on multiple servers in one package. On the subject of vhosts, I'd have to say theirs resemble somewhat of an inside joke that I just didn't get. Also - they filter IRC connections from their machines, so you can only access certain servers on certain IRC networks. KIRE does offer toll-free sales, billing, and technical support, however numerous emails have reported that inquiries regularly go unanswered. They accept US cash, money orders, checks, eChecks, and all major credit cards.

» Reliux Internet Services
Reliux is a relatively new provider that is actually hosted by Lomag at their AboveNet datacenter. Prices are more than competitive, starting as low as $2.99/month. Their vhosts are limited, being that they only have 24 IPs to work with. Reliux's advantage would be in their speed - since they take use of Lomag's superior connectivity. Their server is also fast - an Intel P4 3.2 GHz with 1GB DDR400 RAM and 2 250GB drives! There are many "fly-by-night" providers popping up and I'd have to say Reliux has shown it will not disappear like the rest. They accept all major credit cards via PayPal, as well as checks and money orders.

» Santrex Internet Services Provider
Like JEAH, Santrex has positioned itself to be a full-service provider rather than just a "shell account company". And like Reliux, I think the 3-month old Santrex has potential for longevity. They offer shell accounts, web hosting, file server hosting, and brag the ability to separate each customer-type. That is, if you're a web hosting customer you don't have to worry about DOS from shell server clients. Santrex is headquartered in the UK and is hosted in the Los Angeles area. They plan to soon add a server housed in Europe. They accept Visa/Mastercard, Western Union, PayPal and e-Gold.
