I've noticed a Class A IP address on our Class C network. What does this mean and how can I determine what's causing this? I've can ping and tracert which gives 10.44.10.34 and 10.44.10.33. The DHCP Scope on the DC is 192.168.3.1 - 3.200.

I am looking a old exercise I did last year about subnetting and I am wondering if is possible to subnet:
198.18.9.1 /22
I wrote down, last year, that:
16 bit are assigned to network
6 to subnet
10 to hosts
when actually I see a class C ip address with 10 bit assigned to hosts. So, how many bit do I have for network, subnet and hosts?
why do class D doesn't have subnetmask

I am carving up an internet Class C for customer. This class C is used by 3 distinct QA, Corporate and Production firewalls. I want to carve up IP space so there is a /26 for each environment. The issue I have is the firewalls may need communication with each other via the public IP space. Currently I don’t have any L3 switches in between the firewalls and the edge internet router. So with subnetting, it would seem I need to push everything through the internet router for the intra-firewall communication.I would rather not push this traffic through the edge router, so I came up with an idea to allocate all firewall outside interface IP’s in the 4th (last remaining) /26. That way, I can allow firewalls to communicate over the primary interface IP’s, which will all be in the same subnet – without going through a routing “engine”/device.
For the actual environment subnets (NAT's on respective firewalls), I create a static route on the edge router pointing to each of the firewall’s primary IP’s for the respective environment routes (the first 3 - /26’s).This is still a beta design, but I have done this before on small scale when ISP gave me 2 subnets for example, assuming I was going to put a router in between the customer firewall and ISP. I would use the “routed subnet” on the ASA interface, and then pull the NAT’s from the other subnet. The ISP would have to add a static route directing the NAT subnet to the “routed subnet” correct IP - which would be the firewall outside interface primary IP.I recently found out that with ASA OS 8.4.3 and up, ASA will not proxy arp for IP’s not in its local interface subnet. This means the ISP/router will have to assign static ARP entries on the edge router. This can get messy after the first few NAT entries. So I am debating the design now. I think this kind of stuff going forward won’t be worthwhile with newer ASA 8.4.3 code.
How to communicate between different ASA’s, while still carving up the Class C into usable smaller subnets? The primary reason for doing this in the first place is to support routing on the edge router. I am thinking it might be time to ask for another Class C to do the routing functions, and keep the firewalls all at Layer 2 in one /24 - Class C?
ACS 5.3 always sends the class=cacs:xyz attribute in an authentication response. How can I suppress that behaviour? The Cisco Email Security Appliance doesn't support multiple class attributes (defect 49096) and even treats guest users as administrators.

I was looking at a problem where a traffic from certain sites have a restricted bandwidth, an ongoing problem for a year or so, apparently this throughput never exceeds around 25Mbps. My customer describes a situation where the end to end utilisation rises, eventually flat-lining at around 25Mbps. how many extra systems come on line, this traffic never exceeds this rate, and end users complain of poor responses.
During my investigation I found that one of the switches (Cat 6509) in the traffic path has a policer configured on a vlan interface, the policer has 3 sections for different traffic based on DSCP markers, and a default (unconfigured) class-default. Various people have had a poke about with this config over the years, with the result that all the traffic has the CoS and DSCP tags set to 0. All this traffic is hitting the class-default in the policer.The link that this traffic hits the Cat 6509 on is a 100Mbps link.
If I was designing this from scratch I'd probably configure a rate for the class-default.my question is, in the case where no specific configuration has been entered for the class-default, how much bandwidth is allocated to this class?
I may be replacing my e1550 soon and am looking at both the N750 and N900 class devices. While the EA3500/4500 seem to be a really good deal with a lot of bang for buck, I do have one concern...
As I have zero intention of ever using Cisco Cloud Connect, I would need to stick with the Classic firmware. While Cisco did quickly push out a solution to get the routers back to Classic after the initial Cloud Connect deployment fiasco, I cannot seem to find any commitment from Cisco to continue to support the classic interface (other than "“Cisco will continue to support both local and cloud management options for our customers.”). Even more disconcerting is that the current evidence seems to indicate that they are not. [code]
So, while I do understand that many of the updates have been Cloud Connect specific, some of these changes are in fact global/driver updates. As an example, according to the release notes, on June 25, 2012 the EA3500 CCC firmware v.1.1.38 (Build 138143) updated the WiFi driver, apparently the Classic never received this update.
I'm trying to support a friend. They just switched to TWC Business Class from Megapath. They have a Cisco 5505 ASA and are trying to configure it to work with the new TimeWarner cable modem. But we can't get PCs behind the firewall out to the Internet.
We think it should be a pretty simple config. They have the ASA connected directly to the modem. The modem is running DHCP, and we''ve configured the ASA to get its address via DHCP. We have a Windows server behind the firewall; it can't get out the Internet either. It's set up to be a DHCP server and is giving IP addresses to the PCs on the network.
Laptops connected via wifi to a wireless router attached to the modem are able to connect to the internet, thus we know the modem is up and running fine.
Here's our running config:

I have a requirement to provide stats on a per-department, per-destination basis between sites. If I take Voice as an example I have 5 child classes referring to the 5 departments each matching EF and a particular access-list that matches the department's subnet. I tie these 5 child classes into a parent Voice class-map.
Now when I issue a "show policy-map interface" command I see stats for the parent class-map only whereas I would expect to see a breakdown for each of the child classes which is what is required.
I am doing this on an ASR1002 running 3.2.2.

This router had some default configuration in it's flash, when I bought it. There are class maps.... how it works or how to add/edit rules. Also, do I need to use class maps, or can they be replaced by ACL's to certain extend? How to add/edit class maps rules to allow certain port (eg. 3333). Pease see below part of the default config:

I'm trying to configure a zone-based firewall on an SR520 and am confused about the 'not' criterion. The 'zone-design-guide' says (my stress): Class- maps define the traffic that the firewall selects for policy application. Layer 4 class-maps sort the traffic based on these criteria listed here. These criteria are specified using the match.where my intention is to let only LAN hosts with IPs in the range 192.168.1.1 to 192.168.1.7 out through the firewall. There may be an easier way of doing this which I'd be pleased to hear about. But, even if there is, I'd also be interested to know what I'm doing wrong in the above.

1. login into RV220W admin web
2. Create a VLAN, id 201
3. Go to "Multiple VLAN subnets", select the VLAN, click edit
4. Enter following info:
IP Address: 172.16.0.1
Subnet Mask: 255.255.0.0
DHCP Mode: DHCP Server
Domain Name: Cisco
Starting IP Address: 172.16.2.100
Ending IP Address: 172.16.10.254
Primary DNS Server: 172.16.0.1
Leave rest of settings with default value.
DNS proxy is enabled
5. Press Save button. The UI shows text "IP Address Range -".
Expected result: RV220W shall save the setting and make use of 172.16.0.0 subnet in IP pool. By the way, the error message "IP Address Range -" seems incompleteI tried same setting on netgear FVS318N (very similar settings to RV220W), it accepts 172.16.0.0/16 as DHCP IP pool and works.RV220W has great feature set meets my needs. Its UI is slow and sometime dashboard freezes, which I can live with comparing to features. But DHCP server IP pool can't be class B is huge limitation to me.
Im having a (from google-fu) seemingly unique issue with load balancing. So for background, I am running the ACE 4710 device in "on a stick" mode, so I am using NAT and all that good stuff. I am also utilizing class maps and host header matching so I can save on IP space. [code]
Basically, as soon as I add that ACL_CLASS_beta.mainsite.com class map, all I get back from the ACE is RST packets and it comes back with an L7 LB Policy Miss.
It SEEMS like it should work, but it doesnt seem to like matching on those source addresses at all.
I have a relatively simple question. I would like to create a private network within a larger network, the private network having several clients. I would ideally like the router to appear as the only device on the larger network and all data to be sorted by the router to the clients in the private network.
Will the Netgear FVS318G be able to do that? It seems to have the necessary NAT options.
I have 4 computers (3 laptops, 1 desktop) in a shared office. We get internet access using their wireless network. All works fine. However, I need to share a printer amongst all of the computers. The printer is LAN enabled and I would normally just put all the PCs on a hub, together with the printer and share it that way. BUT my question is can we access the internet using the wireless network and the printer using a separate wired network at the same time?
