The domain-name starts with a digit, which is not really recommended, RFC

due to the fact a valid actual hostname cannot start with a digit,

some MTAs/MUAs, that comply with earlier versions of standards still in us

if the actual hostname is
something legal such as mail.101100010100110.net.
if there is code that old still out there, it desrves to die.
the leading character restriction was lifted when the company
3com was created. its been nearly 18 years since that advice
held true.
Which goes back to one of the standard-provided definitions of domain
name syntax used by RFC 821 page 29:
domain ::= element | element . domain
element ::= name | # number | [ dotnum ]
mailbox ::= local-part @ domain
...
name ::= a ldh-str let-dig
...
a ::= any one of the 52 alphabetic characters A through Z
in upper case and a through z in lower case
d ::= any one of the ten digits 0 through 9
at least three times in the past decade, the issues of RFC 821
vs Domain lables has come up on the DNSEXT mailing list in the
IETF (or its predacessor). RFC 821 hostnames are not the
convention for Domain Labels, esp as we enter the age of
Non-Ascii labels.
Correct but if you want to be able to send email to them then you
*also* need to follow RFC 821 as modified by RFC 1123 so effectively
you are limited to LDLDH*LD*{.LDLDH*LD*}+.
If you want to buy !#$%^*.com go ahead but please don't expect
anyone to change their mail software to support b...@!#$%^*.com
as a email address.
The DNS has very liberal labels (any octet stream up to 63 octets
in length). If you want to store information about a host, in the
DNS, using its name then you still need to abide by the rules for
naming hosts. Yes this is spelt out in RFC 1035.
There are lots of RFCs which confuse domain name with domain
style host name. Or confuse domain name with a host name stored
in the DNS.

In this case almost all forms of detection/prevention except possibly looking at TTL will require new equipment to be deployed at the site(s) anyways based on the information we have, negating much of the extra cost. Any active detection on the RF side of things is generally done using WAPs in a managed network or standalone devices that are pretty much repurposed WAP hardware anyways, but cost a lot more. I think it would be cheaper to have a script written that would grab the ARP table of each site and then compare to what is known. Kind of an ARP tripwire. Sure you'll have to take the time with early runs to hunt down non-company owned MACs but that is going to be a lot cheaper than managing a 130 site roll-out. Even if you did put RF monitoring equipment in each site you would still have to monitor and manage it. Either way, you'll be getting a current inventory of devices. From what I read, he wants to detect non-company equipment on his network. It's just WiFi that is the main problem. Even just watching the DHCP leases, which I assume the little Cisco router is providing, will catch most of the rouge devices. Get someone that knows networking and perl on the task for a month. If they don't have the local talent there are a lot of people that would love to take the contract, considering most of it could be done remotely. Jonathan stated that they have health data on the network and only company issued devices are allowed. I would suggest to him that he inventory the equipment via MAC address (I'm guessing that it's mostly standard issue stuff that would be easy to recognize) and then lock down unused ports and setup up monitoring. If a new MAC appears on the network, then it better have been sent there by IT. -- Joe Hamelin, W7COM, Tulalip, WA, 360-474-7474

Makes me remember when I had my first ISDN line and was happy to get beyond dial-up rates. Second question, though 'real' internet customers all get real IP's, what would you think of doing something like this with 'large scale' nat instead. Understand, we're only talking about basic internet, something like a 256k/96k (or similar) connect, not something that would be used by a serious user. (One thing we are looking at is some older dial up users we still have, most of which could go onto cable just fine but don't want to pay the price). Force SMTP to something sane, block all the 139, etc. MS ports. Basic web, telnet, and ssh. Set it up like a coffee house. Use a proxy and make them register. It's not like they are chatting 911, ya know. If they have NAT issues, then they need a real account. If they can get to google, wikimedia, or what ever a high school student needs to research papers, then they have what they need for a life-line. Let chat protocols through, that's low bandwidth. I'm guessing that this is done as a favor to the customer that won't/can't pay for a real account. But let them know it's not a real account. This is just to give them a taste of real IP and not a solution to all their problems. Shove them a NATted DHCP address and if they can't figure that out then refer them to the local wizkid or a better plan with support.

Re: Which P-Touch should I have?
Give me a link to the labeling section and I'll let you know if I've seen it in the wild. I'm out in the field now (got sick of the desk) and see a lot of commercial/retail plants. I doubt that it's going on in retail, except maybe Lowe's Hardware. They do love MM fiber and just did a nation-wide network upgrade to gigabit everywhere in the stores. But then again, the label specs were kinda hit and miss. Sadly I've seen no IPv6 in any retail shops. -- Joe Hamelin, W7COM, Tulalip, WA, 360-474-7474 On Thu, Feb 16, 2012 at 9:20 PM, Kenneth M.

For cable labeling I've had good results with 3M Scotch Super88 color electrical tape. Pick unique color bands for each cable. Band it identically at both ends. You don't have to squint to see how it's labeled. And the label isn't invalidated merely because you unplugged it from one place and plugged it in somewhere else. I usually use labels printed on all sides in about a 14 point font that have a unique number followed by a - and a length. So, for example, 10294-4.5 is a 4.5' long cable number 10294. You might need to squint a bit to read it, but, 14 points is usually pretty legible and being printed 4 times on the label (3 of which remain visible on the average cat5/cat6 cable) means you usually don't have to futz with twirling the cable to find the label. I usually have the labels installed ~2 from the plug at each end. In a crowded deployment, I think the color bands would be like trying to read resistor color codes in a box of ~1,000 mixed resistors. You're going to end up squinting anyway. With my tactic, you have the additional advantage that you get a defined search radius within which the other end can be located. Using serial-number labels instead of equipment-specific labels means that mine aren't invalidated either. Owen

The two MX sites are connected via third party MPLS. The problem is when one MX site loses Internet connectivity the sending MTA may take up to 4 hours to resend and hopefully the DNS coin toss gives it the address of the site that is still connected. (Read as: French ISPs don't seem as robust as I'm use to in the US.) Since our mail traffic is international something like anycast would be nice. Now the other problem is we don't have an ASN or do external BGP ourselves. And not that it matters in a network sense, but this is a Domino mail system.

Anycast provider for SMTP?
I have a mail system where there are two MX hosts, one in the US and one in Europe. Both have a DNS MX record metric of 10 so a bastardized round-robin takes place. This does not work so well when one site goes down. My solution will be to place a load balancer in a hosting site (virtual, of course) and have it provide HA. But what about HA for the LB? At first glance anycasting would seem to be a great idea but there is a problem of broken sessions when routes change.

Re: DataCenter color-coding cabling schema
I know at Clearwire data centers we used gray for network, blue for management and orange for RS-232 console. At least for the initial build. Later re-work or additions were whatever the tech had on hand ;) They also had labels on each end of each wire showing the path through the system, sometimes up to six lines. It did make it easy to bring up a data center and find cabling errors. To see the system last more than a year or two up upgrades would take some strong rules and oversight.
